| Prof. Armstrong received his B.S. from Washington and Lee University and his M.S. and Ph.D. degrees from Texas A&M University. He has over 420 publications including 22 book chapters, one book (Use of Ordered Media in Chemical Separations) and eight patents. He has given over 410 invited seminars and colloquia worldwide. He is considered the “Father” of pseudophase (micelle and cyclodextrin-based) separations. He elucidated the first chiral recognition mechanism for cyclodextrins. He also first developed macrocyclic antibiotics as chiral selectors. He is one of the world’s leading authorities on the theory, mechanism and use of enantioselective molecular interactions. Over 30 different LC and GC columns originally developed in his laboratories have been commercialized and/or copied worldwide. His work and columns were in part responsible for the chromatography and electrophoresis–lead revolution in chiral separations over the last two decades. This work provided the impetus for the FDA’s regulatory changes regarding chiral drug development in 1992. More recently, he has developed rapid, high efficiency, microfluidic methods for analyzing microorganisms and colloidal particles. Dr. Armstrong also developed the most comprehensive solvation and characterization models for room temperature ionic liquids (RTILs) and pioneered their use in analytical chemistry. |

Before coming to LEAP Technologies, Tom worked as a team leader at a CRO mainly focusing on trouble-shooting high-resolution mass spectrometry analyses of Dioxins and Furans. In his over 10 years of employment with LEAP Technologies, Tom gained valuable experience in the automation of laboratory processes in general with particular emphasis on multi-stream, multi-valve, multi-column, and solid phase extraction applications. With LEAP being a smaller company, Tom is also involved in authoring technical documents, papers, IP submissions, product development, customer problem trouble-shooting and product management. |

| Dr. Wijetunge is a Senior Research Scientist II and a Unit Manager at MicroDose Therapeutx, Monmouth Junction, NJ. He currently heads the analytical method development group supporting dry powder inhalation (DPI) products. In his current position he leads research projects on stability and solid state characterization of API. He received his bachelors’ degree in chemistry from University of Peradeniya, Sri Lanka and Ph.D. in analytical chemistry from Wayne State University, Detroit, MI. He started his career at Battelle Memorial Institute, Columbus, OH in 2001, supporting analytical method development and validation activities for inhalable drugs such as insulin, doxorubicin and isoretinoine. During the same time he took part in developing a safer recombinant anthrax vaccine. From his work at Battelle, he holds a patent in delivering highly insoluble drugs on a nano formulation platform. After 6 years of career at Battelle, Dr. Wijetunge joined Mannkind Corporation where he researched about the effects of surface energy and humidity on dry powder inhalation formulations. He also contributed to the research leading to the increase in shelf life of the finished drug product, insulin. |

| Justin M. Wiseman has a B.S. in Chemistry from the University of Indianapolis and obtained a Ph.D. in Analytical Chemistry specializing in the development and application of novel mass spectrometry instrumentation under the supervision of Professor R. Graham Cooks at Purdue University. Prior to obtaining his Ph.D., Dr. Wiseman worked at Eli Lilly & Co. in Indianapolis, IN as an analytical chemist in support of parenteral manufacturing. Dr. Wiseman is a co-inventor of desorption electrospray ionization (DESI) and desorption atmospheric pressure chemical ionization (DAPCI), both ionization methods used in ambient mass spectrometry. He has published over thirty high impact peer reviewed manuscripts and book chapters on the development and applications of DESI mass spectrometry, including the development of its capability for imaging biological tissue samples. While at Purdue University, Dr. Wiseman completed a two-year NSF fellowship, received the Schering-Plough Science and Innovation Award, and obtained a certificate in business management from the Krannert School of Management under the Applied Management Principles program. He is currently Director of Research and Development at Prosolia, Inc., an Indianapolis, Indiana based company specializing in the commercialization of sample introduction methods and atmospheric pressure surface sampling techniques for mass spectrometry. Dr. Wiseman’s research interests include atmospheric pressure desorption/ionization techniques and applications thereof in bioanalytical chemistry and forensics, imaging mass spectrometry, and microfluidics. |
