David A. Weitz

David A. Weitz is the Mallinckrodt Professor of Physics and Applied Physics at Harvard University, holding joint appointments in the Department of Systems Biology and directing the Harvard Materials Research Science & Engineering Center. He also co-directs the Harvard Kavli Institute for Bionano Science & Technology and the BASF Advanced Research Initiative. His research focuses on soft condensed matter, biophysics, and microfluidics, with applications in materials science, drug delivery, and high-throughput screening. Weitz earned his B.Sc. from the University of Waterloo (1973), and A.M. and Ph.D. in Physics from Harvard (1975, 1978). After roles at Exxon Research and the University of Pennsylvania, he joined Harvard in 1999.

• Affiliations: Harvard University (Primary), TUM-IAS (Former Hans Fischer Senior Fellow, 2008).
• Key Appointments: Director of Harvard Materials Research Science & Engineering Center, Co-director of Harvard Kavli Institute.

Research interests span colloidal systems, biomaterial mechanics, and microfluidic engineering for encapsulation and diagnostics. His lab pioneered microfluidic droplet techniques for creating designer emulsions and high-throughput assays. Current projects include biocompatible nanocapsule design, CO₂ mineralization, and studying biomolecular condensates in cells.

Publications highlight advances in colloidal glasses, liquid crystal defects, and droplet deformation physics. Awards include Fellowships from the American Physical Society, Optical Society, and Biophysical Society, alongside prestigious lectureships (e.g., Jean Perrin Lecture).

Grant activities include collaborations with industry and initiatives like The Salata Institute for Climate and Sustainability. His lab supports interdisciplinary training, with recent milestones including PhD defenses and microfluidics-based sustainability projects.
