Between academic discovery and product development lurks a lull in research funding that inventors call the “chasm of death,” where a prototype or a proof of concept can feel just out of reach.To address that development gap, five projects initiated by faculty at Harvard’s John A. Paulson School of Engineering and Applied Sciences and in the Faculty of Arts and Sciences have been selected to receive funding of between $70,000 and $100,000 each, through Harvard’s Physical Sciences & Engineering Accelerator (PSE Accelerator).The funding is designed to support a burst of activity on a specific project to bring it to a development milestone at which an industrial partner or investor might become engaged, for example, by sponsoring further research, licensing the technology, or launching a company.“The ability to attract an industrial or venture partner is often ‘make or break’ for an emerging academic technology, if you want to see it become a useful product in the outside world,” said Mick Sawka, a director of business development in Harvard’s Office of Technology Development (OTD). “We’ve found that a relatively small amount of very targeted support can help faculty demonstrate that a new invention is ready to break out of the lab.”Professor David Weitz has developed a microfluidics platform to analyze and sort nanoliter-sized droplets of liquid or gel.

Over the course of the year, investigators work toward predefined milestones, with access to industry advisers, dedicated guidance from OTD on intellectual property protection, and a comprehensive commercialization strategy that encourages entrepreneurship.The projects receiving support from the accelerator this year:— Stephen Chong, professor of computer science, has created a shell scripting language, called Shill, that offers strong and flexible security for complex tasks such as system administration, through a combination of programming language design and “sandboxing” technology. Developed with postdoctoral researcher Christos Dimoulas and graduate student Scott Moore, Shill could improve the security of enterprise and cloud-based system administration.— Graduate student Frederick Chang, in the engineering and physical biology track of the Department of Molecular and Cellular Biology, and his mentor Nancy Kleckner, Herchel Smith Professor of Molecular Biology, have invented a highly sensitive pattern-detection algorithm that, in combination with a suitably designed microscope, will enable three-dimensional time-lapse imaging of living systems at the molecular scale. By giving researchers a better view inside cells, the system could, for example, enhance the process of evaluating drugs for clinical trials.— Charles Lieber, Mark Hyman Jr. Professor of Chemistry and chair of the Department of Chemistry and Chemical Biology, has invented polymer-like mesh electronics and a method of delivering the electronics by syringe injection into living organisms. These biocompatible electronic implants can be used to record activity from and deliver electrical stimulation to the nervous system, and could potentially be used to treat neurological and neurodegenerative diseases.— David A. Weitz, Mallinckrodt Professor of Physics and Applied Physics, has developed a microfluidics platform to analyze and sort nanoliter-sized droplets of liquid or gel. These droplets are ideal for functional analysis of individual cells. The platform will enable rapid isolation of immune cells that recognize infected or cancerous cells.— George M. Whitesides, Woodford L. and Ann A. Flowers University Professor, has invented a paper-based respiration sensor that can characterize sleep apnea. Combined with wireless electronics, the sensor could transmit results to a health care professional, enabling diagnosis of sleep apnea at home and at low cost, with less need for conventional sleep studies in the initial characterization.“The research projects stand out for their imagination and creativity,” said Senior Associate Provost Isaac T. Kohlberg, Harvard’s chief technology development officer. “Each one is challenging the state of the art in science, technology, or health care. The accelerator model we’ve pioneered through the Physical Sciences & Engineering Accelerator and the Blavatnik Biomedical Accelerator takes a strategic approach to advancing technologies like these while they’re still in the lab, incubating them a little longer to ensure they thrive.”The PSE Accelerator has catalyzed the launch of several startup companies in recent years, including Voxel8, RightHand Robotics, Calculario, and Validere, as well as licenses to companies such as Green Energy Storage, which is developing a flow battery technology.OTD will begin accepting preproposals for the next round of funding in mid-summer. The recipients are selected by an advisory committee.
