Guigen Liu, PhD

Assistant Professor of Radiology

Guigen is an Assistant Professor in the Department of Radiology at Brigham & Women’s Hospital (BWH) and Harvard Medical School (HMS). Trained as both a mechanical and optical engineer, Dr. Liu has an extensive prior research background in optical fiber sensing for non-biomedical applications. He and colleagues invented a silicon-tipped optical fiber sensing platform, which won the Alan Berman Research Publication Award from the U.S. Naval Research Laboratory and is currently being commercialized by a startup. Since joining BWH and HMS, Dr. Liu has transitioned to apply his expertise in fiber optics to tackle challenges in the biomedical field. He has established research programs on developing and translating multi-modality microendoscopy, with applications spanning personalized healthcare, disease diagnosis, interventional radiology, and beyond. Dr. Liu is the recipient of an NIH/NIBIB K25 award and a BWH Radiology Department Research Pilot Award.

Clara Steiner, MD

Post-doctoral Research Fellow

Clara is a postdoctoral research fellow at the Jonas Lab and the Lank Center for Genitourinary Oncology at the Dana-Farber Cancer Institute, where she is working with Dr. Toni K. Choueiri and Dr. Wenxin Xu. She completed her medical school at the University of Leipzig in 2020 and finished her fourth year of urology residency at the University Hospital in Leipzig, Germany. In the Jonas lab, she is mainly involved in the clinical trials examining implantable microdevices in renal cell carcinoma and bladder cancer. Outside of work, Clara enjoys playing tennis, modern and urban dance, and skiing.

Vincenzo Tarallo, PhD

Post-doctoral Research Fellow

Vincenzo Tarallo completed his Master and PhD at University of Naples “Federico II” in Industrial Biotechnology, focusing on protein engineering applied to different protein families. During his postdoc at the Charles University, he developed with his colleagues a high-throughput screening assay for the direct evolution of sulfoxide reductases, using the in vitro evolution of the methionine sulfoxide reductase A (MsrA) as proof of concept. Prior to joining the Jonas Lab in 2024, he was a postdoctoral researcher at the CWRU conducting studies on mouse models in order to elucidate the role of D-types cyclins on tumor promotion with a focus on myeloproliferative neoplasms. He is currently interested in studying the tumor microenvironment changes in response to drug treatment in vivo, analyzing the crosstalk among the cancer cells and the immune cells.

Sajanlal Panikkanvalappil, PhD

Scientist

Sajanlal Panikkanvalappil is a Scientist at Brigham and Women’s Hospital and holds an appointment at the Dana-Farber Cancer Institute. He earned his Ph.D. in Chemistry from the Indian Institute of Technology Madras, where he was honored with the Langmuir Award for the best thesis. Following his PhD, he advanced his research as a Postdoctoral Fellow and Research Scientist with Prof. Mostafa El-Sayed at Georgia Institute of Technology. His research focuses on pioneering methods for synthesizing advanced nanomaterials, creating ultrasensitive sensors, and developing nanotechnology-based, minimally invasive cancer imaging and therapeutic modalities. His significant contributions to surface-enhanced Raman spectroscopy have unveiled new vibrational biomarkers, offering critical insights into various biomolecular events. His current research is dedicated to devising novel implant-assisted tumor-targeting strategies and clinically viable implantable microdevices for cell delivery and screening. Additionally, he serves as an institute PI and co-investigator on a NASA grant supporting the Artemis mission, aiming to understand the best survival mechanisms during exposure to cosmic radiation and microgravity for future human space exploration beyond low Earth orbit.

Fanni Santa, MD

Post-doctoral Research Fellow

Fanni received her M.D. from the University of Szeged Albert Szent-Györgyi Medical School in Hungary. During her studies, she conducted full-time research at the Department of Pathology, focusing on the pathological, diagnostic and molecular assessment of genitourinary tumors, specifically in the kidney, prostate, and bladder. She also served as a histology instructor for three years, teaching third-year medical students in both general and organ-specific pathology.
In 2024, Fanni joined the Jonas Lab where she focuses on the pathological assessment of drug responses in various malignancies, including head and neck, kidney, bladder, and ovarian carcinomas. Beyond her dedication to pathology and education, Fanni is passionate about art, enjoys both modern and classical music, and loves trail running.
