Principal Investigator


Nitin Joshi, PhD

Dr. Nitin Joshi is an Assistant Professor at Harvard Medical School and an Associate Bioengineer in the Department of Anesthesiology, Peripoperative and Pain Medicine at the Brigham and Women’s Hospital. After obtaining his PhD degree in Biomedical Engineering from Indian Institute of Technology Bombay, India, he did his postdoctoral fellowship at the Brigham and Women’s Hospital with Dr. Jeffrey Karp. Dr. Joshi’s main research focus is drug delivery and biomaterials. Technologies developed by him have resulted in 10+ granted and pending patents and technology disclosures, with most licensed to biotech companies and one already advancing through clinical trials. Dr. Joshi’s research work has been published in top tier journals, including Nature Communications, Science Advances, Nanotoday, Biomaterials, and Journal of Controlled Release, and has been highlighted by multiple media outlets and scientific journals around the world. He has received multiple awards for his work, including MIT’s Technology Review Magazine (TR35) India Award, Lockheed Martin Innovation Award, and Boston Patent Law Association (BPLA) 2020 Invented Here! Featured Honoree Award. Dr. Joshi has keen interest in training and mentoring the next generation of biomedical scientists and has mentored more than 30 students to date.

Postdoctoral Fellows


Jingjing Gao, PhD

Jingjing joined the Joshi Lab as a postdoctoral research fellow in May 2021. She is co-mentored by Dr. Nitin Joshi and Dr. Jeffrey Karp. She completed her PhD in Chemistry at University of Massachusetts Amherst in 2019 and continued as a Postdoc for one year. Her research interests include stimuli-responsive materials for sensing and drug delivery. In Joshi Lab, her focus is to develop drug delivery platforms and maximize their translation potential for osteoarthritis treatment. In her spare time she enjoys traveling and exploring new restaurants. 


Sohyung Lee, PhD

Sohyung joined the lab as a postdoctoral research fellow in April 2022 right after she completed her Ph.D. in Chemical Engineering at UCLA under the mentorship of Prof. Dino Di Carlo. She is co-mentored by Prof. Nitin Joshi and Prof. Jeffrey Karp. Her research interests broadly include developing micro/nano-fabrication methods for biomedical applications. During her Ph.D. she worked on 3D bioprinting and microfluidics for tissue engineering and single cell analysis. Currently, her focus is to develop drug delivery platforms for long-lasting drug release for different applications. In her free time, she enjoys watching images and videos of cute animals and she likes walking in warm weather.

Dongtak Lee, PhD


Dongtak joined the lab as a postdoctoral research fellow in September 2022, under the mentorship of Drs. Nitin Joshi and Jeffrey Karp. Dongtak completed his Ph.D. in Biomedical Engineering at Korea University with Prof. Dae Sung Yoon where he focused on fabricating various biomaterials for biomedical applications. During his Ph.D. course, he developed nanoparticle-based drug screening platforms for treating neurodegenerative diseases and cell membrane-based biosensors. Currently, his research interests broadly include developing drug delivery platforms for translational medical applications. In his free time, he enjoys going for a walk and hanging out with friends and family.


John Joseph, PhD


Dr. John Joseph is a Postdoctoral Fellow co-mentored by Drs. Nitin Joshi and Jeffrey Karp. He has broad research interest in nanomedicine and nanotechnology with an emphasis on polymeric drug delivery systems and biomedical implants. In the Joshi Lab, John’s research focuses on leveraging biomaterials to develop stimuli-responsive hydrogels and long-acting injectables. During his Ph.D in nano-bioengineering, John developed novel biomaterials for vascular graft applications. This study was undertaken at Amrita Centre for Nanoscience, India, in collaboration with the University of Bristol, UK.
