John Mellors, MD                                                                       Co-PI

Professor of Medicine and Chief, Division of Infectious Diseases
Endowed Chair for Global Elimination of HIV and AIDS

Recruiting and mentoring more than 25 faculty to build a top academic ID Division and HIV/AIDS Program, Dr. Mellors is the PI of the NIH DAIDS-funded Pitt Clinical Trials Unit and directs the Virology Cores for the NIH DAIDS-funded AIDS Clinical Trials Group (ACTG) and the Microbicides Trials Network (MTN). Within the ACTG, he has served as the Chair of the HIV Reservoirs and Eradication (Cure) Transformative Science Group (TSG), overseeing the development of an innovative research agenda to address critical knowledge gaps and to test innovative therapeutic approaches toward a cure of HIV-1 infection. The Mellors laboratory investigates the mechanisms of viral persistence and strategies to deplete or control viral reservoirs, and is highly-experienced in i) sensitive quantitative PCR assays for viral DNA and RNA forms, ii) sequencing to characterize persistent virus populations, and iii) performing virus induction and infectious outgrowth assays. Dr. Mellors has mentored more than 15 predoctoral (PhD and MD) students, postdoctoral PhD research associates, and MD Fellows in the laboratory and in clinical research, and he serves on numerous PhD dissertation committees, offering trainees balanced guidance in translational research, authorship, scientific presentation and grant preparation.

Solomon Ofori-Acquah, PhD                                                    Co-PI

Associate Professor of Medicine, Division of Hematology-Oncology
Associate Professor of Human Genetics
Principal Investigator, Pittsburgh Heart, Lung, Blood, and Vascular Medicine Institute
Dean, School of Biomedical and Allied Health Sciences, University of Ghana

Classically trained as a hematology and molecular genetics scientist in the National Health System in England, Dr. Ofori-Acquah described the RFLP haplotype of the sickle chromosome among sickle cell disease (SCD) patients in England for the first time and determined the functional relevance of polymorphism of a short tandem repeat in the beta-globin locus control region on HbF level in SCD. His expertise in functional genomics was central to defining the role of a polymorphic cyclic AMP response element in the gamma globin gene in induction of HbF3. Currently, Dr. Ofori-Acquah’s research ranges from basic and translational studies in animal models to large-scale genomics studies of SCD patients in the H3Afrcia consortium. His studies on Nrf2 indicate that this transcription factor plays a dominant role in slowing down progression of SCD with aging. Thus, Nrf2 is an attractive therapeutic target for lessening the severity of SCD chronically. The Ofori-Acquah lab has also recently found that by promoting “low-grade” disease phenotype, Nrf2 activation protects transgenic SCD mice from developing acute lung injury during episodes of hemolytic crisis.

In addition to research, Dr. Ofori-Acquah has a well-documented commitment to teaching, having mentored 19 students at pre-doctoral and postdoctoral levels, six junior faculty, two medical students, seven undergraduate students, and one high-school student. As Co-Director on the VMI T32 training grant, he has overseen the recruitment of minority fellows committee and will leverage this leadership experience as Co-PI on this K12 program grant.

Ivona Vasile-Pandrea, MD, PhD             Comorbidities Track Leader

Professor of Pathology
Professor of Infectious Diseases and Microbiology

During the last 17 years, Dr. Pandrea has developed numerous new animal models for the study of progressive, nonprogressive, and elite controlled SIV infections. Her research in non-human primate (NHP) models of AIDS resulted in the development of new paradigms of SIV pathogenesis. Supporting Dr. Apetrei, Dr. Pandrea’s laboratory was involved in the only large-scale studies assessing the biology of SIV in the wild and the main modalities of SIV transmission in natural hosts. During the last years, she has performed NHP studies with multiple therapeutic interventions, including antibiotics or various diets, whose impact on the NHP microbiome was monitored. These studies pointed to differences in the microbiome between AGMs and macaques. The Pandrea laboratory developed the needed tools for the study of SIV pathogenesis and transmission in AGMs, with a focus on mucosal sites. She has also investigated the role of microbial translocation and inflammation in HIV-associated co-morbidities including cardiovascular disease and hypercoagulability. Additionally, Dr. Pandrea has a strong history of training and mentoring both graduate and medical students, as well as postdoctoral fellows.

He is past President of the Infectious Disease Society of America, the founding chair of the NIH-CDC-IDSA Guideline on Management of Opportunistic Infections in Persons with HIV Infection, and Co-Chair of IDSA/AASLD Guidance on Management of Hepatitis C.

Dr. Masur’s research program has been an integrated basic science and clinical program, focused heavily on pulmonary complications of life-threatening disease. He has written seminal investigations into the pathogenesis, treatment and prevention of Pneumocystis pneumonia, His program were leaders in recognizing that Pneumocystis is a fungus rather than a protozoon, that it has enzymes that can be targets for novel therapeutic agents, and these unique proteins are ideal targets for novel diagnostics. His group has been leaders in sequencing rodent Pneumocystis, and now human Pneumocystis, which will open new avenues for understanding the unusual biology and epidemiology of this clinically important organism. He has worked as well on other pulmonary pathogens including CMV and Cryptococcus. He oversees research in non-HIV lung disease including ARDS and influenza pneumonia

Dr. Masur leads the District of Columbia Partnership for AIDS Progress (DC PFAP), a unique collaboration between NIH and the DC government which aims to create an urban model for decreasing the impact of HIV/AIDS on underserved populations. DC PFAP is focusing on HCV-HIV co-infection with the goal of improving understanding of host and viral factors that determine disease progression and response to therapy and reducing the burden of disease in an inner city population. The program has built a partnership of community-based clinics that work with the NIH-Clinical Center to follow over 1000 patients with HCV or HIV/HCV. The program has one of the largest treatment programs in the world using investigational HCV drugs. The program has pioneered studies on the optimal duration of therapy and the optimal drug combinations. Important publications on host factors of response are included in the 30+ HCV publications from the past 3 years including publications in high impact journals such as JCI, JID, CID, JAMA, Annals of Internal Medicine, and Lancet. This program is a model for how to work with hard to reach patient groups and communities.

The DC Partnership has highlighted the importance of metabolic syndrome in HIV/AIDS. This has led to the early stage development of a basic and translational program to understand the etiology, consequences, and intervention that might be relevant to managing the clinical syndrome. The metabolomics, microbiomic and genomic aspects of this program have relevance to projects focusing on several HIV co-morbidities.

Dr. Masur has worked closely with industry partners in developing new drugs for Pneumocystis pneumonia, CMV disease, HIV, and HCV. His extensive experience working with industry will provide valuable contacts and valuable perspectives for a program project grant focused on translational research.

Dr. Masur has also worked closely with the FDA. He served for over a decade as chair of the FDA’s Antiviral Advisory Committee. He currently works closely with FDA staff on drug development, on national programs such as antibiotic resistance, and on national guideline committees. This experience will serve drug development strategies well.

During the past 25 years, Dr. Masur’s department has launched the careers of dozens of academic leaders, many with NIH funding. His program graduates are in high demand at academic institutions and include senior leaders in industry and the FDA, chief medical officers, division and department heads, presidents of major professional societies, and members of ASCI and AAP. This mentorship experience will facilitate the success of the Inner-City rotation focus, which he will direct, and provide a strong leadership presence in the Maryland site of this grant.

Steve Chan, MD, PhD

Professor of Medicine, Division of Cardiology
Principal Investigator, Pittsburgh Heart, Lung, Blood, and Vascular Medicine Institute
Director, Center for Pulmonary Vascular Biology and Medicine

Dr. Chan studies the molecular mechanisms of pulmonary vascular disease and pulmonary hypertension (PH), an example of an enigmatic disease where reductionistic studies have primarily focused on end-stage molecular effectors. To capitalize on the emerging discipline of “network medicine,” research in the Chan laboratory utilizes a combination of network-based bioinformatics with unique experimental reagents derived from genetically altered rodent and human subjects to accelerate systems-wide discovery in PH. In doing so, Dr. Chan’s published work was the first to identify the systems-level functions of microRNAs (miRNAs), which are small, non-coding RNAs that negatively regulate gene expression, as a root cause of PH. Dr. Chan also has expertise in the study of extracellular microRNAs and their delivery to recipient tissue for modulation of gene expression. He has a long-standing interest in HIV and studied its molecular entry mechanisms as part of his PhD. Dr. Chan collaborates with Drs. Ambrose and Morris on an R01 examining pulmonary hypertension in HIV-infected individuals. Dr. Chan has a strong track record for training post-doctoral fellows in cardiovascular research, with a number of his trainees going on to establish independent academic research careers as principal investigators. Dr. Chan is committed to his role as faculty member of this career development grant and continuing his mentorship of these postdoctoral fellows.

Liza Villanueva, MD

Professor of Medicine, Division of Cardiology
Director, Center for Ultrasound Molecular Imaging and Therapeutics
Vice Chair for Pre-Clinical Research, Department of Medicine

Dr. Villanueva’s research focuses on the development of medical diagnostic and therapeutic strategies based on ultrasound and ultrasound contrast agents (gas-filled microspheres, or microbubbles). Her work has consistently bridged fundamental imaging sciences with translational biomedical research. As an Established Investigator of the American Heart Association, she has been a leader in the development of microbubbles for the assessment of myocardial perfusion and ultrasound molecular imaging with targeted microbubbles for the detection of inflammatory and angiogenic endothelial markers in pre-clinical models of heart disease. The Villanueva lab has pioneered the development and application of microbubbles as molecular probes and acoustic detection strategies for optimizing imaging sensitivity. They have applied fundamental principles of ultrasound and the physics of microbubble acoustic behaviors to develop novel targeted molecular therapeutics, whereby nucleic acid loaded microbubbles (siRNA, miRNA, plasmid), in the presence of precisely tuned ultrasound, selectively enhance membrane permeability and deliver payloads to the target site. These studies are conducted at the Center for Ultrasound Molecular Imaging and Therapeutics, a translational multidisciplinary research facility that epitomizes the reciprocal relationship between imaging sciences and biomedical translational research. Moreover, Dr. Villanueva has a recent R01-funded collaboration with Dr. Pandrea, a fellow mentor on this proposal, as to how ultrasound molecular imaging may evaluate endothelial activation in HIV pathogenesis, which may prove useful for potential trainees of this grant.

JoAnne Flynn, PhD  

Professor of Microbiology and Molecular Genetics

Dr. Flynn has worked in the field of tuberculosis research for 25 years, including post-doctoral training in Dr. Barry Bloom’s lab where she initiated studies in the immunology of tuberculosis (TB) using knockout mice. Fifteen years ago, Dr. Flynn began the development of non-human primate models of TB, and she has used this model for studies in the pathogenesis and immunology of Mycobacterium tuberculosis infection. The Flynn lab has demonstrated that cynomolgus macaques naturally present with the full spectrum of M. tuberculosis infection outcomes seen in humans, from latent to active infection, and replicate the pathology of human TB. She has used this model to study pathogenesis, immunology, pathology and interventions (drugs, vaccines, immunodulation) with great success, and she has devised several unique methods for analyzing these monkeys. The Flynn lab has also developed methodology and analytics tools for incorporating PET/CT into their studies for serial tracking and quantitative readouts of infection and disease progression. Using a PET/CT scan as a map, the Flynn lab obtains individual granulomas and other more complex pathologies for ex vivo analysis, which is unique to her lab. She has developed methodology and scoring systems used by many in the field for pathology and bacterial burden, and her lab is seen as expert in non-human primate models of tuberculosis. Dr. Flynn has extended her studies into additional non-human primate models, including rhesus macaques and the common marmoset.

Dr. Flynn has substantial experience in training graduate students, post-docs, and medical fellows, having served as Director of the Molecular Virology and Microbiology Graduate Program for 5 years and on the Admissions Committee for 6 years.

In the mid-1990s, Dr. Charurat was an active investigator in the NIH-funded Women and Infants Transmission Study (WITS) when mother-to-child HIV transmission was fairly high in the U.S., and in the early 2000s, he pioneered the mobile recruitment platform that successfully provided PEPFAR services to key populations such as female sex workers, men who have sex with men, and higher-risk pregnant women. Dr. Charurat published a first molecular characterization of circulating HIV-1 infections in Nigeria and is working with the CDC and the GON to improve incidence rate determination and surveillance across different populations in Nigeria. Currently, he is PI on three NIH R01 grants: MARGIN characterizes microbiome among HIV-Exposed but uninfected infants in Nigeria; Building TRUST targets marginalized MSM and determine intervention for treatment as prevention (TasP) and pre-exposure prophylaxis ARV (PrEP); and ADAPT is an HIV adolescent transition to adult care study. Additionally, he just completed another R01 studying barriers to engaging MSM in services in Nigeria. Furthermore, Dr. Charurat is PI of a CDC-funded PEPFAR evaluation grant entitled: “Strengthening HIV Field Epidemiology, Infectious Diseases Surveillance, and Lab Diagnostics Project.” As a mentor on this grant, Dr. Charurat intends on training the next generation of investigators and can provide experiences in both the Inner-city HIV and International HIV focus areas.

Bernard Macatangay, MD

Assistant Professor of Medicine, Division of Infectious Diseases
Assistant Director, University of Pittsburgh Immunology Specialty Lab (ACTG)

The overall goal of Dr. Macatangay’s research is to further define the immunoregulatory network and inhibitory checkpoints involved in HIV-1 infection to investigate their role in chronic inflammation and HIV latency, and to devise successful immune therapeutic strategies to decrease chronic inflammation and contribute to HIV-1 cure. He is the Laboratory PI and the Co-PI of two NIH/NIAID U01 grants: one investigating the role of the adenosine suppression pathway in chronic HIV-associated inflammation and one focusing on a comparative analysis of dendritic cell-based vaccine strategies for functional cure of HIV. As the Laboratory PI, Dr. Macatangay is responsible for the overall coordination of the laboratory aspects of the projects and in developing and directing all the immunoregulatory lab assays that are performed in his laboratory. Additionally, he is the Assistant Director of the University of Pittsburgh ACTG Immunology Specialty Laboratory and the Clinical Laboratory Director of the University of Pittsburgh Clinical Research Site. He also serves as the Protocol Immunologist in 5 ACTG Cure Protocols, A5315 (Romidepsin for activation of HIV-1 expression), A5321/A5341s (Decay of HIV-1 reservoirs in subjects on long-term ART), and A5342 (VRC01 on HIV persistence), A5370 (Anti-PD1 anitbody in HIV), A5374 (therapeutic vaccine with conserved HIV-1 immunogens), and two ACTG Inflammation studies, A5286 (Rifaximin as a modulator of microbial translocation) and A5325/A5330s (Isotretinoin on immune activation in blood and gut tissue). Additionally, Dr. Macatangay is the protocol Co-chair of ACTG A5347s which involves sampling anatomic compartments in participants who will undergo a monitored antiretroviral pause. An elected member of the ACTG HIV Reservoirs and Viral Eradication TSG, he also serves as an investigator in the Multicenter AIDS Cohort Study (MACS), where he chairs the Viral Immune Pathogenesis Working Group.

Sharon Riddler, MD

Professor of Medicine, Division of Infectious Diseases
Director of Clinical Research, Division of Infectious Diseases

With more than 20 years of experience in clinical research funded by the NIH and industry, Dr. Riddler is the Co-PI of the NIH/DAIDS-funded Pitt-OSU HIV/AIDS Clinical Trials Unit and has been the Site Leader for the University of Pittsburgh Clinical Research Site (affiliated with both the AIDS Clinical Trials Group and the Microbicide Trials Network) since 2006. Dr. Riddler is responsible for implementation of all trials conducted at the Pitt CRS for the ACTG, MTN, and other sponsors. She is well versed in clinical trial design and protocol development, having been Chair or Co-Chair for several network studies in the ACTG (A5115, A5142, A5276s, A5342, and A5374) and MTN (MTN-015 and MTN-003B), as well as a protocol in development (MTN-039) for a safety and pharmacokinetic study of an elvitegravir rectal insert for HIV prevention. Moreover, she is Co-PI for two U01 funded pilot studies in HIV: a recently completed trial of dipyridamole for immune activation, and a newly funded study of dendritic cell based therapeutic vaccination.

Charles Rinaldo, PhD

Professor and Chair, Infectious Diseases and Microbiology
Professor of Pathology

Dr. Rinaldo’s basic research laboratory focuses on studies of innate and adaptive immunity in the immunopathogenesis of HIV and human herpesvirus 8 (KSHV) infections linked to the Multicenter AIDS Cohort Study and AIDS Clinical Trials Group (ACTG). Dr. Rinaldo also directs an Immunology Specialty Laboratory in the ACTG focused on cell immunity, regulation and immune activation in the ACTG HIV Reservoirs, and Viral Eradication Transformative Science Group. His HIV research centers on the dynamics of dendritic cell-T cell interactions leading to anti-HIV immune reactivity as a model for immunotherapy of antiretroviral drug treated HIV-1 infected persons, with the ultimate goal of eradicating their HIV reservoir. Dr. Rinaldo’s clinical specialty is diagnostic virology, with emphasis on molecular methods for rapid detection of herpesvirus and influenza virus infections. He has primary responsibility for diagnostic molecular virology in the UPMC Clinical Microbiology Laboratory that serves over 30 regional hospitals and associated clinical sites and has advised numerous postdoctoral fellows and graduate students in these areas of research. As chair of the Department of Infectious Diseases and Microbiology and the founding PI of the Pittsburgh Multicenter AIDS Cohort study, Dr. Rinaldo will help provide a strong pipeline of candidates for post-doctoral training in the K12 program.

Thomas Smithgall, PhD

William S. McEllroy Professor and Chair, Department of Microbiology and Molecular Genetics

Dr. Smithgall’s research interests are centered on the role of protein-tyrosine kinase signaling pathways in cancer, HIV/AIDS, and embryonic stem cell differentiation. His research program is interdisciplinary, integrating techniques of chemical genetics, biochemistry, molecular biology and biophysics to gain insight into the role of kinase signaling pathways in ES cell fate, cancer and AIDS. For more than 25 years, graduate students and postdocs have played a critical role in all of the Smithgall lab’s research efforts, and mentoring has been one of the most rewarding aspects of his career. Graduate Program Director for the Biochemistry and Molecular Genetics Graduate Program of the Interdisciplinary Biomedical Graduate Program (IBGP) for six years, and as member and chair of the admissions committee for the IBGP, Dr. Smithgall has mentored nineteen graduate students (PhD/MD-PhD) and 14 postdocs have completed research in his laboratory to date, with four Ph.D. students and two postdocs currently under his mentorship. All of Dr. Smithgall’s trainees have published and gone on to careers in basic research (industrial and academic), clinical medicine, STEM education, or science and public policy.
