Senior Principal ScientistAlcon (Powervision) Jun 2018 - PresentPowerVision was purchased by Alcon (HQ in Ft Worth TX). Post acquisition, I was invited to continue with the R & D team that was developing an intraocular lens (AIOL) in Belmont, CA. Our interdisciplinary team is focused on post implant adjustment (PIA) for AIOL. My role includes preparation & investigation of novel materials for PIA as well as the application & troubleshooting of those materials. Also conceptualization and documentation of intellectual property regarding PIA / AIOL materials.

Senior ScientistNanosys, Inc. Mar 2008 - Apr 2016Milpitas, Ca, UsSince being founded in 2001 Nanosys has become a profitable small company with the first product, quantum dot enhancement film (QDEF), on the market and more products on the way... I was one of five people on the initial nanocrystal phosphor team when I returned in March 2008 and helped develop QDEF. • Conceptualized and synthesized 7 novel polydentate oligomeric stabilization ligands for semiconductor nanocrystals, Coordinated those ligands onto nanocrystals- Built these ligands using 8 inexpensive starting materials such as styrene maleic anhydride copolymer, polyacrylic acid, trisilanol polyhedrial oligomeric silsesquioxane (POSS) and trichlorosilane- Applied classical organic synthesis techniques to produce oligomeric ligands functionalized with solubilizing groups and polydentate nanocrystal binding groups - Coordinated those novel ligands to Group II-VI and III-V semiconductor nanocrystals- Transferred multistep synthetic methodology for 7 novel organic compounds to specialty chemical manufacturers. • Filed 19 invention disclosures and assisted patent attorneys with technical assistance for filing patents, one patent issued was, QDEF, the product • Assisted other areas of the company with laboratory expertise and technical skill -
Senior ScientistAllaccem, Inc. Jun 2006 - Feb 2008A start up company dedicated to commercializing an antimicrobial compound to be used against gram positive & gram negative bacteria as well as mold. After about 18 months the company transformed into a veterinary care products company and now sells three products. - Conceptualized and synthesized of 4 novel bactericidal organic molecules - Responsible for scale up from milligram to multi-gram quantities for these compounds- Filed 2 invention disclosures and assisted patent attorneys with technical assistance
