Parnian Ahmadi, Ph.D.
PI: Xiang-Yang Wang, Ph.D., professor
Education: I earned my Master's and Ph.D. in medicine and veterinary medicine, specializing in parasitology and immunology, from Miyazaki University, Japan.
Research: Acetaminophen (APAP) overdose remains a leading cause of acute liver failure, with limited treatment options beyond N-acetylcysteine (NAC). This study investigates the role of fatty acid oxidation (FAO), specifically through carnitine palmitoyltransferase 1A (CPT1A), as a novel protective and regenerative mechanism in APAP-induced liver injury. Using hepatocyte- and macrophage-specific CPT1A knockout mouse models, we explore how FAO modulates cytotoxic stress, immune responses, and liver regeneration. We also evaluate a novel AMP-activated protein kinase (AMPK) agonist to therapeutically enhance fatty acid oxidation (FAO) activity. These findings aim to uncover new metabolic strategies for treating APAP toxicity and improving liver recovery outcomes.
About me: When I’m not in the lab, you can find me hiking local trails, capturing nature through photography or experimenting with new recipes in the kitchen. I find that time outdoors fuels my creativity and brings balance to my life. I also enjoy science communication and mentoring, which help me stay connected and inspired both inside and outside the lab.

Thuy An Nguyen, Ph.D., Postdoctoral Fellow
PI: Xiang-Yang Wang, Ph.D., professor
Education: I earned my medical doctorate degree from the University of Medicine and Pharmacy in Ho Chi Minh City, Vietnam, and subsequently completed a Ph.D. in medicine, specializing in immunology, at the University of Yamanashi, Japan.
Research: My current research focuses on optimizing T cell therapy for bone metastasis tumors. I am fascinated by the concept of T cell therapy as a “living drug” which is capable of persisting in the body and providing long-term control over disease. This idea of durable, self-sustaining immunotherapy continues to drive my passion for research in this field. I am also interested in deciphering the components of the tumor microenvironment and how they influence patients’ susceptibility to immunotherapy.
About me: My hobby is fishing. In my opinion, fishing closely resembles doing experiments. For me, in both fishing and experimentation, success lies in the process of observation, patience, and learning from the unexpected.

Ali Gawi Ermi, Ph.D.
PI: Devanand Sarkar, Ph.D., professor
Education: Ph.D. in chemical biology, Virginia Commonwealth University
Research: My research focuses on evaluating the efficacy of novel treatment strategies using nanoparticles in liver cancer. This project focused on using nanotechnology to deliver small interfering RNA (siRNA) that is specifically targeted to treat tumor cells in the liver, a form of targeted gene therapy. In this research, two genes were targeted: Astrocyte Elevated Gene-1 (AEG-1) and Staphylococcal Nuclease Domain-Containing Protein 1 (SND-1), both of which are overexpressed in various cancers, including those affecting HCC patients.
About me: When I'm not in the lab, I love spending my free time with family and engaging in outdoor activities, such as playing soccer and swimming. I also enjoy traveling and exploring new places, as well as meeting new people.

Dandan Huang, Ph.D., T32 Postdoctoral Associate
PI: Sarah Spiegel, Ph.D., professor
Education: Ph.D. in clinical discipline of Chinese and Western integrative medicine, Peking University
Research: My primary research focus is on lysosome function mediated by the bioactive sphingolipid metabolite ceramide in the context of glomerular injury and sclerosis. As I progressed in my career, I found myself increasingly drawn to cancer biology and oncology, and particularly the roles of bioactive sphingolipid metabolites. My research interests now are on the connection between metabolic disorders and pancreatic cancer, the most lethal cancer with an extremely poor survival rate.
About me: I enjoy exploring new experiences together with my family.

Maryam Jamil, Ph.D., Postdoctoral Fellow
PI: L. Ashley Cowart, Ph.D., professor
Education: Ph.D. in human and molecular genetics
Research: My research focuses on elucidating the role of non-canonical sphingolipids in hepatocellular carcinoma (HCC), with particular emphasis on how these atypical lipid species contribute to tumor progression and liver metabolic dysregulation. Using hepatocyte-specific genetic models and lipidomics, I investigate the functional impact of altered sphingolipid biosynthesis pathways. A central aim is to understand how enzymes like SPTLC3 drive the production of non-canonical sphingolipids and influence oncogenic signaling. This study aims to identify novel metabolic vulnerabilities in HCC that may inform future therapeutic strategies.
About me: When I'm not in the lab, you can usually find me running after my energetic toddler — being a mom of three keeps me constantly on my toes! While it’s tough to find time for traditional hobbies, I enjoy winding down with a good TV show or scrolling through YouTube. These simple moments help me recharge and bring a bit of balance to my busy life.

Anna Kovilakath, Ph.D., T32 Postdoctoral Fellow
PI: Lauren Cowart, Ph.D., professor
Education: Ph.D. in human genetics, Virginia Commonwealth University; M.S. in human genetics, Virginia Commonwealth University; B.Sc. in biotechnology, Manipal University
Research: My research investigates how aromatase inhibitors (AIs), commonly used in hormone receptor-positive breast cancer, contribute to atherosclerosis and cardiovascular risk. I utilize in vitro and in vivo models to investigate AI-induced alterations in vascular cell behavior, plaque progression, and macrophage function. A major focus is on the role of sphingolipids, particularly SPTLC3-derived species, in mediating these effects. This work bridges basic lipid biology with translational cardio-oncology, aiming to uncover mechanisms of AI-associated cardiotoxicity and identify potential therapeutic targets.
About me: When I'm not in the lab, you can usually find me rock climbing, reading or going on walks with my husband and our two dogs. I also enjoy quiet evenings, cuddled up with a good book and our cat, mTOR. These hobbies help me unwind and maintain a healthy work-life balance.

Li Li, Ph.D.
PI: Suyun Huang, Ph.D., professor
Education: PhD in Oncology, Tongji University
Research: My research broadly focuses on epigenetic mechanisms in glioblastoma. I am interested in how changes in histone modifications, and RNA-based regulation contribute to tumor development, stemness, and treatment resistance. By studying these processes, I aim to gain a deeper understanding of glioma biology and uncover potential strategies for therapeutic intervention.
About me: Outside of research, I enjoy traveling, exploring nature, and experiencing different cultures. I also like photography and spending quiet time reading or relaxing with music.

PI: Brian (Binks) Wattenberg, Ph.D., professor
Education: Ph.D. in biochemistry and molecular biology, Virginia Commonwealth University
Research: My research focuses on understanding the mechanisms by which serine palmitoyltransferase (SPT), the first and rate-limiting enzyme in the de novo sphingolipid biosynthesis pathway, is regulated by its regulatory subunit, the ORMDLs. I am especially interested in the functional implications of ORMDL-based regulation of SPT in central nervous system (CNS) myelinating glial cells, such as oligodendrocytes, and skin keratinocyte cells.
