MEET THE TEAM

Karthikeyani Chellappa PhD

Principal Investigator

Department of Molecular Microbiology and Immunology

Center on the Biology of Aging

Karthi started her lab at Brown University in May 2023. Karthi is a hard-core metabolism enthusiast. Karthi is leading her team to tackle the biology of aging from the perspective of the host and host-microbiome interactions using an array of interdisciplinary approaches with a goal of identifying interventions to promote healthy aging. She is also passionate about inter-organ communications and systemic metabolism. She looks forward to connecting with researchers near and far.  In her free time, Karthi loves to read, scout out new restaurants, and relax with friends and family.

Tony is a  trained organic chemist. He began his career extracting and testing the antibacterial properties of medicinal compounds from plants native to the Peruvian Andes mountain region. He synthesized and tested small molecule probes for various proteins implicated in diseases like diabetes, cartilage degradation and the bubonic plague during his graduate studies. He currently runs the LC-MS instrument for metabolomics in the Chellappa Lab. He likes organic gardening and cooking. He also likes to bike and boat.

Youngjae Jo

Incoming Postdoctoral Researcher

Hello, I am Narendra and I come from the mountains (Nepal). I am an enthusiastic aging researcher/graduate student in the MCB department/Center on the Biology of Aging at Brown. Currently, I am working on identifying and understanding the metabolic pathways relevant to biological age. I am dedicated to unraveling the complexities of aging and discovering novel avenues for enhancing healthspan. Outside lab, I love watching/playing soccer and hanging out with friends. I look forward to connecting with people out there.

Ian Freezman

Research Assistant (Part-time)

IMG_2644.jpg

 Hello, I am a part-time Research Assistant specializing in LC-MS. Originally from Syracuse, NY, I graduated from Rochester Institute of Technology with a BS in Biotechnology and Molecular Biology in 2022. I spent 3 years as an undergraduate researcher working on isolation of bacterial antibiotics. I currently work for Q2 Solutions where I started as an LC-MS Scientist and have since moved out of the lab to the role of Project Leader. Outside of work I enjoy hiking, skiing, playing guitar, watching sports, and spending too much time playing video games.

Raphael Angelo Ignacio Zambrano

Incoming Research Assistant

Sample Headshot.jpg

Hello, Raphael here. I’m an incoming RA from the Brown University PREP program who graduated from Cal State Northridge majoring in Biotechnology/Medical Technology as well as Cell and Molecular Biology. From my experiences tackling antibiotic resistance with synthetic biology tools in undergrad, to examining a bacterial/viral co-infected lung model in my post-baccalaureate program, I continue to engage with my interests in the microbiology field and I look forward to learning more participating in research involving the microbiome. Aside from science however, I occasionally enjoy sightseeing and definitely trying new foods out there (so don’t hesitate to throw me a recommendation).
