gel-e management team & advisors

Larry Tiffany is Chairman of the Board of gel-e. Larry is a serial entrepreneur having most recently founded and led to the sale of the neuro-molecular testing company DioGenix. While at the helm of DioGenix, Larry raised over $12M from early stage investors while garnering another $2M in non-dilutive sources (e.g. the National MS Society) to support the clinical development and prospective validation of the first new diagnostic for Multiple Sclerosis since the late 50’s, MSPrecise®. Prior to DioGenix, Larry held positions in Sr. Management at Ore Pharmaceuticals (CBO), Gene Logic (SVP & GM, Genomics) and Genetraks (US President). He holds a JD from Franklin Pierce Law Center in Concord, New Hampshire (specializing in intellectual and commercial law); a MS in Biotechnology from Johns Hopkins University in Baltimore, Maryland; and a BS in Biochemistry from Nazareth College in Rochester, New York.

Matthew Dowling, Ph.D. is Founder and Chief Scientific Officer of gel-e. Matt completed his graduate work at the Fischell Department of Bioengineering at the University of Maryland in May 2010 and has since pursued gel-e on a full-time basis. In 2005, after graduating in chemical engineering from the University of Notre Dame, he was awarded the Fischell Fellowship in Biomedical Engineering for his innovative ideas in drug delivery systems. Matt then co-created the gel-e platform, raising $165,000 in initial grants to develop the technology, which led to being named the Dean’s Doctoral Research Award from the UMD Clark School of Engineering for his work on chitosan-based self-assembled soft materials for use in wound treatment. He has since successfully licensed gel-e from UMD and has raised another $2.0M in non-dilutive funding which has been astutely used to achieve a first FDA clearance for gel-e, a large and growing patent estate and numerous peer-reviewed publications in high-impact journals.

Rich Vincent is the Chief Financial Officer of gel-e. Rich previously held senior management positions at Meritage Pharma, Sorrento Therapeutics, Elevation Pharmaceuticals, Verus Pharmaceuticals, Women First HealthCare, Elan Pharmaceuticals, Phase Metrics, and Deloitte & Touche LLP, where he specialized in emerging growth and publicly-traded companies. Over the past 20+ years, Rich’s experience includes raising over $550 million through venture capital, major commercial banks and institutions, public offering proceeds for high growth pharmaceutical and technology-based companies, and participating in a number of acquisitions and divestitures valued at over $1 billion. Rich was named 2014 public company CFO of the Year in San Diego by the San Diego Business Journal.
