Sangeeta N. Bhatia (born 1968) is an American biological engineer and the John J. and Dorothy Wilson Professor at MIT’s Institute for Medical Engineering and Science and Electrical Engineering and Computer Science (EECS) at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts, United States. Bhatia's research investigates applications of micro- and nano-technology for tissue repair and regeneration. She applies ideas from computer technology and engineering to the design of miniaturized biomedical tools for the study and treatment of diseases, in particular liver disease, hepatitis, malaria and cancer.[1]
Bhatia's dissertation became the basis for Microfabrication in tissue engineering and bioartificial organs (1999).[9]
Bhatia co-authored the first undergraduate textbook on tissue engineering, Tissue engineering (2004), written for senior-level and first-year graduate courses with Bernhard Palsson.[10]
She was a co-editor of Microdevices in Biology and Medicine (2009)[11]
and Biosensing: International Research and Development (2005).[12]
Early life and education
Bhatia's parents emigrated from India to Boston, Massachusetts; her father was an engineer and her mother was one of the first women to receive an MBA in India. Bhatia was motivated to become an engineer after her 10th grade biology class and a trip with her father into an MIT lab to see a demonstration of an ultrasound machine for cancer treatment.[13]
Bhatia currently directs the Laboratory for Multiscale Regenerative Technologies at MIT and is affiliated with Brigham and Women's Hospital and the Koch Institute for Integrative Cancer Research.[20]
Bhatia is a strong advocate for gender equity and inclusivity in STEM fields.[21]
Bhatia helped to found the Diversity Committee of the Biomedical Engineering Society, and is involved with MIT's Society of Women Engineers.[1] While at MIT, she helped to start Keys to Empowering Youth, a program that brings middle-school girls to visit hi-tech labs as a way to encourage them in science and technology.[22] Bhatia and her husband, Jagesh Shah have two daughters.[13][22]
In 2015, Bhatia was elected a member of the National Academy of Engineering for tissue engineering and tissue regeneration technologies, stem cell differentiation, and preclinical drug evaluation.
Research
Bhatia's doctoral work focused on the development of a way to keep liver cells functioning outside of the human body.[23] She adapted ideas from computer chip design and engineering to the microfabrication of a substrate for liver cells.[24]
She successfully applied techniques from photolithography to petri dishes, to create a substrate that would support growth of a functioning microliver in a dish.[1][24][25]
Bhatia also used co-cultures of more than one cell type to prevent dedifferentiation of the liver cells, building on the work of Christiane Guguen-Guillouzo in France.[24]
She and her coworkers have also used techniques from 3D printing to create a lattice of sugar as a framework for a synthetic vascular system with the goal of supporting larger tissue structures such as an artificial liver.[26]
Her work was one of the first projects at MIT in the area of biological micro-electromechanical systems, or Bio-MEMS.[24][27] She is interested in using arrays of living cells as high-throughput platforms to study fundamental aspects of Bio-MEMS in stem cells.[27][28]
Bhatia's research in the Laboratory for Multiscale Regenerative Technologies (LMRT) continues to apply micro- and nanotechnology ideas to tissue repair and regeneration.[29]
She studies the interactions between hepatocytes (liver cells) and their microenvironment and develops microfabrication tools to improve cellular therapies for liver disease in an approach referred to as hepatic tissue engineering.[30][31]
The goal is to maximize hepatocyte function,[32][33]
facilitate design of effective cellular therapies for liver disease,[30] and improve fundamental understanding of liver physiology and pathophysiology.[34]
The approach has been used to study diseases including hepatitis and malaria.[1][35]
Bhatia's laboratory is also involved in a multidisciplinary effort to develop nanomaterials as tools for biological studies and as multifunctional agents for cancer therapies.
Interests center around nanoparticles and nanoporous materials that can be designed to perform complex tasks.
They may be able to home in on a tumor, signal changes in cells or tissues, enhance imaging, or release a therapeutic component.[38]
In 2002, Bhatia worked with Erkki Ruoslahti and Warren Chan to develop phage-derived peptide-targeted nanomaterials, or quantum dots, for in vivo targeting of tumors.[24][39][40]
By adding tumor-enzyme molecules to nanoparticles she has also created specialized nanoparticles that can react with diseased tissue to create synthetic biomarkers detectable in blood or urine samples.[41] Another project involves engineering beneficial probiotics with the ability to detect or treat cancer cells.[1]
Bhatia holds a number of patents for both clinical and biotechnological applications of engineering principles.[38] In 2015, her company Glympse Bio received initial funding from Kiran Mazumdar-Shaw and Theresia Gouw at Aspect Ventures. In 2018, Glympse received $22 million to further develop “activity sensors” to identify diseases and monitor patient response to drugs.[42]
2015, Heinz Award, Heinz Family Foundation, in the Technology, the Economy and Employment category "for her seminal work in tissue engineering and disease detection, including the cultivation of functional liver cells outside of the human body, and for her passion in promoting the advancement of women in the STEM fields."[47]
