The Division of Infectious Diseases at Harbor-UCLA has a very active and robust research program that includes training of post-doctoral fellows in a variety of disciplines within Infectious Diseases. Over the past three decades, numerous fellows from all over the world have completed post-doctoral training in our Division and have gone on to successful careers in Academic Medicine and Industry. Our post-doctoral fellows are an integral part of our academic Division and work in our on campus research center, the Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center (Lundquist Institute).

Selvi Esroy, Ph.D.

Dr. Ersoy is a Postdoctoral Research Fellow, working for Dr. Arnold Bayer, MD, in the Division of Infectious Disease at the Lundquist Institute for Biomedical Innovation the Harbor-UCLA Medical Center.  She received her B.S. in Genetics with a minor in Medical Anthropology from UC Irvine in 2010 before heading to UC Santa Barbara for her graduate studies.  At UC Santa Barbara, she earned her M.A. and Ph.D. in Molecular, Cellular, and Developmental Biology with an emphasis in Microbiology in the laboratory of Dr. Michael Mahan.  There, she studied the influence of host microenvironments on antibiotic susceptibility in a variety of microbial pathogens.  Dr. Ersoy joined the Bayer Lab in 2017, where she has focused her research on the influence of bicarbonate, our body’s primary biological buffer, on β-lactam susceptibility in Methicillin-Resistant Staphylococcus aureus (MRSA).  Her research investigates genetic and phenotypic mechanisms through which bicarbonate alters MRSA susceptibility to clinically relevant β-lactams, and the in vivo relevance of this phenomenon is a rabbit model of infective endocarditis.  The aim of her research is to improve antimicrobial susceptibility testing procedures and standard treatment practices for MRSA.

Liana Chan, Ph.D.

Dr. Chan is a Postdoctoral Fellow in the Division of Molecular Medicine at Harbor-UCLA Medical Center.  She earned her Ph.D. in Infectious Diseases & Immunity from the University of California, Berkeley and trained under Dr. Henry F. “Chip” Chambers at the University of California, San Francisco.  There, she studied molecular mechanisms of ceftaroline and ceftobiprole resistance in methicillin-resistant Staphylococcus aureus (MRSA).  In 2014, she joined the lab of Dr. Michael Yeaman at Harbor-UCLA.  Here, Dr. Chan has focused on understanding the host response to recurrent MRSA infections by utilizing immunological, molecular, cellular and microbiological techniques.  She has published 11 peer-reviewed research papers and was awarded a Postdoctoral Fellowship Grant from the American Heart Association.

Yiyou Gu, Ph.D.

Dr. Gu is a Postdoctoral Fellow working in the Division of Infectious Diseases at the Lundquist Institute and Harbor-UCLA Medical Center. He earned his bachelor degree in Animal Science and Technology Department from Nanjing Agricultural University located in Nanjing, China. Then he received Ph.D degree in Biological Science from Michigan Technology University, trained in Dr. Guiliang Tang’s Lab, there he studied gene silencing, miRNA function and pathway in plant system. In 2017, he joined Dr. Ashraf S. Ibrahim’s lab, where he focusing the research in human pathogenic fungi, in particular, he is working on pathogenic gene function study in Mucorales species.
