Principal Investigator

Nitin Joshi, PhD

Instructor of Anesthesia

Dr. Nitin Joshi is an Instructor of Anesthesia 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

John Joseph, PhD

Dr. John Joseph is a Fulbright 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, Dr. Joseph’s research focuses on leveraging biomaterials to develop stimuli-responsive hydrogels and long-acting injectables. During his Ph.D in nano-bioengineering, Dr. Joseph 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.

Anthony Yu, PhD

 Dr. Anthony Yu joined the group in November 2020 after he finished his PhD at Stanford University where he focused on engineering injectable and sprayable hydrogels for delivery of therapeutics and fire retardants. He is co-mentored by Dr. Jeffrey Karp and  interested in using materials engineering to improve biomedical therapies.

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 the 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. 

Research Assistants/Interns

Helna Baby Mary

Helna joined the group in November 2020. Her current work focuses on engineering hydrogels and other novel biomaterials for intranasal and inhalation drug delivery. She received her Master’s in Nanomedicine from Amrita Centre for Nanoscience, India, where she developed cell-instructive nanofibrous scaffolds for biomedical applications. Outside the lab, Helna enjoys painting and playing violin.

Kabir Swain

Kabir is currently an undergraduate student pursuing a B.S in Electrical Engineering and Computer Science from KTH Royal Institute of Technology, Sweden. His current research interests are in HCI, neural interfaces, computer vision for medical imaging diagnoses and assistive robotics. He joined the group in January 2021 as a research intern, and is working with Dr. John Joseph on computational modeling for biomedical applications.

Olivia Snapper

Olivia is currently studying as an undergraduate at the University of Texas at Austin focusing on a Biomedical Engineering career. Olivia joined the group in June 2021 as a research trainee. She is working with Dr. John Joseph to engineer next generation hydrogels for nasal drug delivery.  Her research interest are drug delivery, tissue engineering, and pharmaceutical bioengineering.

Julian Kage

Julian is a rising senior at Choate Rosemary Hall, with a keen interest in biotechnology and biomedical engineering. Julian joined the group in June 2021 as a research trainee and is working with Dr. Anthony Yu to develop nanoparticles for drug delivery to the brain. He currently plans to pursue a degree in biomedical engineering or medicine.
