Rachel Perry, PhD

Rachel earned her Ph.D. and completed her postdoctoral training at Yale in the lab of Dr. Gerald Shulman, where she focused on the development and application of novel stable isotope tracer methods to model hepatic metabolism under physiological and pathophysiological conditions. In her own lab at Yale, Rachel studies how metabolism intersects with various physiological and pathophysiological states, including cancer and inflammation. This is, quite sincerely, her dream job.

Rachel’s CV (updated 8/11/22) can be found here.

High school, undergraduate, and postgraduate students

Isaac Kaba (remote undergraduate student)

Isaac is a senior at the University of Toledo, Ohio, pursuing a BS in Pharmaceutical Sciences with a major in Medicinal and Biological Chemistry. His research interests include cancer biology, targeted therapies, and drug discovery, and in the Perry lab he will be performing multi-Omics analysis of publicly available data, aiming to develop new targets for cancer. 

Dennis Owusu (remote postgraduate student)

Dennis is a recent graduate of Kwame Nkrumah University of Science and Technology in Ghana, and a remote member of the Perry lab. His work involves image and RNAseq analysis in liver and tumor, aiming to identify metabolic programs important in both homeostasis and pathophysiology.

Sita Kottilil (Yale undergraduate student)

Sita is a sophomore at Yale, interested in biology, who has recently joined the Perry lab. She will be working on understanding how exercise slows tumor growth in breast cancer, with the goal of identifying new mechanisms by which we can improve the efficacy of standard breast cancer treatments.

Gautham Ramshankar (remote high school student)

Gautham is a high school student working remotely with the Perry lab. Mentored by Ryan Liu, he is examining substrate preference in cancer utilizing publicly available databases.

Ryan Liu (remote high school student)

Ryan is a high school senior working remotely with the Perry lab. He earned the prestigious NIDDK summer student fellowship in 2022, and works on several projects related to exercise and cancer, and utilizing a multimodal dataset to gain a deeper understanding of how tumor fatty lipid metabolism affects outcomes in breast cancer.

Graduate students

Ngozi Akingbesote (PhD student)

Ngozi is a third year graduate student in Cellular & Molecular Physiology, completing her PhD in the Perry lab. She is expertly juggling multiple projects related to metabolic scaling, metabolic therapy for breast cancer, and how the response to immunotherapy for breast cancer may be modulated by exercise.

See: Akingbesote et al. Communications Biology 2022.

Andin Fosam (PhD student)

Andin is an MD/PhD student completing her graduate work in Cellular & Molecular Physiology in the Perry lab. She is interested in better understanding the metabolic crosstalk that is crucial to optimizing health in physiology and pathophysiology.

See: Fosam & Perry Current Opinion in Nutrition and Metabolic Care 2020.

Zongyu Li (PhD student)

Zongyu is a fifth-year PhD student in Cellular & Molecular Physiology. Before the end of his research rotation, he was already producing publishable-quality FACS data (!), and has not slowed down from there. Zongyu’s two projects include delving into how a novel inflammatory mediator may improve hypoglycemia counterregulation, and understanding a metabolic pathway that may drive renal cell carcinoma using REGAL (REnal Gluconeogenesis Analytical Leads).

Susana Nakandakari (visiting PhD student)

Susana is a nutritionist and a visiting PhD student from Brazil. She is mentored by Dr. Dennys Cintra in Brazil, and co-mentored by Dr. Perry and Dr. Andrew Wang here at Yale. Working with this multidisciplinary team, Susana is interested in how systemic metabolism affects outcomes in sepsis, and an expert in cecal ligation and puncture (no easy feat!).

Yanitza Rodriguez (PhD student)

Yanitza is a first-year PhD student at Yale who has decided to pursue her doctorate in the Perry lab, although as a former Yale postgrad, she has collaborated with our lab for 4+ years now! Yanitza’s project seeks to understand the mechanisms of metabolic dysfunction in polycystic ovarian syndrome, with the goal to generate new lifestyle or supplement recommendations for rodents (with implications for people!) with PCOS.

Xinyi Zhang (PhD student)

Xinyi is a fourth-year Ph.D. student in Cellular & Molecular Physiology. She rotated in the lab during the COVID-19 pandemic, and we were delighted that she has decided to stay! Her project focuses on the use of metabolic therapy in melanoma, a tumor type that has traditionally not been associated with metabolic changes but has given us some interesting hints of metabolic vulnerabilities that may be exploitable. Additionally, based on her own observations, Xinyi has devised a new metabolic therapy to treat cancer-related fatigue.

Staff Scientists

Stephan Siebel, MD, PhD

Dr. Siebel has considerable experience (and doctorates) in flux methodology and genetics. In the Perry lab, he works to understand how alterations in various metabolic pathways promote cancer pathogenesis. In addition, he is our local mass spec expert – a skill which cannot be undervalued! – and has developed all of the LC/MS methodologies we use for internal studies and collaborations in the area of central carbon, fatty acid, and amino acid metabolism.

Wanling Zhu

Wanling is a research technician who works 20% of the time in the Perry lab. She has been a crucial participant in hundreds of our in vivo mouse studies and is a skilled surgeon: few people we know can place a catheter in a vein that’s just 0.2 mm wide with almost 100% survival rate, but Wanling can!

Vijayavalli Thangaraj Panneerselvam, BDS

Dr. Thangaraj Panneerselvam is a dentist and a master’s student at the University of New Haven. She has joined our lab through the Community Research Fellows program and works on projects related to systemic metabolism and cancer.

Azia Bunn

Azia Bunn is a member of the Perry lab through the Yale Cancer Center’s Community Research Fellows program. She is interested in science communication, and she will be helping us improve our manuscripts so as to explain our science to the community more effectively!

Lab Alumni

Aray Beisenbayeva (remote high school student, 2020-21)

Aray is a high school student in Kazakhstan. She worked with Shyryn Ospanova to perform a data analysis project to better understand the social and biochemical determinants of prognosis in lung cancer.
