Dr. Correa is a neuroendocrinologist studying the effects of reproductive hormones on temperature, energy balance, and metabolic health, with the goal of understanding weight gain and hot flashes that often occur in menopause. To understand the mechanisms by which estrogens alter homeostasis, the Correa group focuses on the following broad questions: How does the brain regulate temperature and energy balance? How do homeostatic neural circuits differ between males and females? How are homeostatic circuits modulated by estrogens? The Correa lab combines genetically engineered mice and new viral tools to define the neurons that drive estrogen-responsive and sex-specific changes in energy balance. This approach allows us to dissect the effects of estrogen on distinct neuronal populations with spatial, molecular, and temporal specificity. Dr. Correa earned a BA in biology from Pomona College and a PhD in neurobiology and behavior from Cornell University. Since starting her lab UCLA in 2016, Dr. Correa has been named a Kavli Fellow by the National Academy of Sciences in 2020, one of 100 Inspiring Hispanic/Latinx Scientists in America by Cell Press & Science Signaling Technology in 2020, and an Allen Distinguished Investigator by the Paul G.

Dr. Covarrubias is a macrophage biologist with expertise in immuno-metabolism, and how inflammation and metabolism are integrated to regulate metabolic health and disease states including aging, NAFLD, cancer, and cardiovascular disease. Dr. Covarrubias is a first-generation college graduate from Los Angeles, CA. He received his BS in biochemistry from UCLA, a PhD from Harvard University, and trained during his post-doc at UCSF/Gladstone Institute/ and the Buck Institute of Aging. Dr. Covarrubias identified the nutrient-sensing Akt-mTORC1 pathway as a critical regulator of macrophage polarization. He also showed that activation of the Akt target ACLY  catalyzes the increase in macrophage cytosolic/nuclear pools of acetyl-CoA. These findings suggest how nutrient and metabolic status can fine-tune macrophage function via nutrient sensing pathways. Dr. Covarrubias’ recent work is focused on how diet and aging-related inflammation impacts the aging process. In a recent manuscript he showed that the decline of NAD+ during aging is driven by the activation of tissue resident macrophages via senescent cells. As senescent cells progressively accumulate in aging tissues, these results highlight a new causal link    between visceral tissue senescence, NAD+, and immuno-metabolic dysregulation during aging, an active area of investigation in the Covarrubias Lab at UCLA.

Dr. Gupta completed a PhD degree in psychology, followed by an APA accredited clinical internship at Massachusetts General Hospital/Harvard Medical Center. Her programmatic line of research focuses on the interactions between environmental and biological factors in shaping neurobiological phenotypes associated with stress-based diseases such as obesity. Broadly defined, her research aims to integrate two systems (the brain and the gut) in order to better understand the underlying mechanisms associated with obesity and altered ingestive behaviors. The application of a “systems biology” approach to her research allows her to test the interactions between multiple factors, both inside and outside the body (e.g., sex, race, brain, microbiome, inflammation, environment), in order to better understand the complex pathophysiology of obesity. This is relevant to obesity, as it is a risk factor for many chronic diseases, and disproportionately affects ethnic minorities and women. These alarming projections have led to NIH and Healthy People 2020 priority initiatives directed at reducing ethnic and sex disparities. Her goal is to develop a comprehensive model that provides a powerful and sensitive biomarker that will increase biological readouts of obesity and altered ingestive behaviors, thus bringing to the forefront those individuals who are at increased risk as a result of disadvantaged backgrounds. She recently received a R01 grant from NIMHD (NIH) on the “Social Isolation and Discrimination as Stressors Influencing Brain-Gut Microbiome Alterations among Filipino and Mexican American.” She has also received several industry funded grants as PI and till date she has published over 70 peer-reviewed articles.

Dr. Ke’s primary research interest is focused on understanding the fundamental mechanisms underlying liver ischemia and reperfusion injury (IRI), a major cause of hepatic dysfunction and failure following liver transplantation, resection, and hemorrhagic shock. It is recognized that IRI activates liver macrophages (Kupffer Cells) to generate reactive oxygen species (ROS), leading to inflammatory injury in the liver. Recent studies revealed that activation of the NLRP3 inflammasome required ROS-dependent NEK7, a serine-threonine kinase involved in mitotic cell division. NEK7 directly binds to NLRP3 and promotes inflammatory response. The overall goal of Dr. Ke is to dissect the functions and molecular mechanisms by which Heat-shock factor 1 (HSF1) regulates NEK7 function in liver IRI. In addition to this ongoing project supported by the National Institutes of Health (NIH), Dr. Ke has extended his research to investigate the mechanistic roles of lipid metabolism and innate immune response in nonalcoholic steatohepatitis (NASH). Emerging evidence has indicated lipid-induced oxidative stress involving activation of endoplasmic reticulum (ER)-resident adaptor protein stimulator of IFN genes (STING), a central player in initiating innate immune and proinflammatory signaling. Increased STING expression was observed in Kupffer cells in patients with NASH and a mouse model of high-fat diet-induced steatosis. The overarching goal of this study is to elucidate the molecular mechanisms of immune-metabolic interactions in NASH progression. Recent publications from Dr. Ke’s lab highlight the key role of STING as a regulator of lipid metabolism. Dr. Ke has served as a principal investigator in several NIH grants and has received many investigator awards from the American Society of Transplantation, the American Society of Transplant Surgeons, and The Transplantation Society. He is currently an editorial board member of Hepatology and an associate editor of Frontiers in Transplantation.

Dr. Kupiec-Weglinski received his medical degree from Warsaw Medical Academy, Poland, and a PhD in transplantation immunology from Polish Academy of Sciences. Then, he spent 18 years working in experimental organ transplantation at the Brigham and Women’s Hospital at Harvard University. Since being recruited to UCLA in 1997, he has been leading basic and translational research at the Dumont-UCLA Transplantation Center, one of the largest liver transplantation programs in the country. The Kupiec-Weglinski Lab has been at the forefront of cutting-edge research and several advancements in transplantation that have contributed to its current level of success. His contributions to the field fall into three principal categories: 1/ the discovery of key biological pathways responsible for organ innate immune-driven peritransplant stress and alloimmune mediated rejection response; 2/ the development of novel therapies that control these pathways; and 3/ solving one of the most vexing problems in transplantation, i.e., how to improve the quality and number of organs available for life-saving surgery. In search for refined personalized treatment, his Lab has also pioneered translational research on the role of microbiota and bacteriophage therapy in liver transplantation, as well as vascularized composite allografts. Dr. Kupiec-Weglinski published over 250 peer-reviewed original papers, 70 reviews, 40 chapters, and one book. His research for the past 35 years has been continuously funded by NIH. He was a Member, Board of Directors, American Society of Transplantation; a Standing Member, Transplantation-Tolerance-Tumor Immunology (TTT) NIH Study Section; and a frequent Ad-hoc reviewer for NIH and DoD. He is the recipient of American Society of Transplantation/Astellas Established Investigator Award; Awards from the International Transplantation Society for Outstanding Achievements in Basic Science; and Mentorship/ Education and Training; and holds Honorary Doctorate (“Honoris Causa”) from his alma mater in Warsaw, Poland. Dr. Kupiec-Weglinski is the founding editor in chief of Frontiers in Transplantation and serves as associate editor to Current Opinion in Organ Transplantation. Dr. Kupiec-Weglinski Profile

Dr. Lipshutz received his medical degree from the University of California Los Angeles School of Medicine and completed his postgraduate training at the University of California San Francisco School of Medicine. Dr. Lipshutz is a professor within the Department of Surgery and the Department of Molecular and Medical Pharmacology. He is also a member of the Intellectual and Developmental Disabilities Institute at UCLA along with the Broad Center; he presently holds the Goldwyn Chair clinically. Within the David Geffen School of Medicine, he was previously the Chair of the Academic Medicine College. His clinical specialty and interests include solid organ transplantation. His laboratory focuses on developing and gene and cell therapies for single gene metabolic disorders of the liver. These conditions typically cause brain injury with intellectual disability and he has developed several mouse models and preclinical therapies to treat these disorders primarily focusing primarily on specific urea cycle and creatine deficiency disorders. He serves as an editorial board member of Gene Therapy, Molecular Therapy, and Molecular Therapy-Methods and Clinical Development. Dr. Lipshutz has been an invited participant in multiple NIH conferences and has served as a grant reviewer for both the Wellcome Trust and the US National Institutes of Health where he served as a standing member of the GDD and DBTD study sections.

Dr. Lusis’ lab studies naturally occurring genetic variations in mice and in humans to help understand interactions underlying complex cardiovascular and metabolic disorders. A major focus of the lab has been integrate clinical traits with “intermediate" phenotypes obtained using high throughput technologies such as RNA sequencing, metabolomics, or proteomics, an approach known as "systems genetics" (Seldin et al. 2019 Nature Metab. 1:1038-1050). To facilitate this approach, they have developed a reference resource termed the Hybrid Mouse Diversity Panel (HMDP) that can be used to carry out whole-genome association mapping and analyze complex genetic interactions (Norheim et al. 2019 Cell Metab. 29; 1-18). Current research projects include atherosclerosis, heart failure, fatty liver disease and obesity. Lusis Lab
