Todd E. Mlsna, Ph.D.

Chairman of the Board, Founder

In February of 2003 Dr. Mlsna co-founded Seacoast Science, Inc., where he was President and CTO. Dr. Mlsna’s work has been presented at scientific conferences and published in journals and books on numerous occasions. While at Seacoast he has won several grants from government agencies including the Department of Defense and the Department of Homeland Security for the development of chemical microsensors.

Dr. Mlsna graduated with a B.S. from Albion College in Albion, Michigan in 1985, and a Ph.D. from the University of Texas at Austin, in 1991. Both degrees were in chemistry. His graduate work focused on synthetic organic fluorine chemistry, as did his postdoctoral work at Clemson University.

From 1994 to 1998 Dr. Mlsna worked at the Naval Research Laboratory (NRL), Washington, DC, on the development of absorbent polymer-film-based chemical sensors. While working at NRL his paper ‘Aromatic Fluoroalcohol Coatings for Chemical Warfare Agent Detection’ won Best Paper at the International Sensor Conference in Beijing in 1998 and his work on pulsed laser deposition of polymer films won recognition in 2000 as one of the year’s best patent applications.

In 1998 he joined Sensor Research and Development Corporation where he continued his work on chemical sensor development as Director of Analytical Chemistry. He held the position of Senior Staff Scientist at Graviton from 2000 to February 2003 where he developed polymer formulations for Graviton’s volatile organic compound sensor system.

Dr. Mlsna joined the chemistry faculty at Mississippi State University in 2009.  [...]

William Tolley

William K. Tolley, Ph.D.

Principal Scientist

Dr. Tolley has made a career as a research scientist and manufacturing manager emphasizing innovative chemical sensor technology. As a Principal Scientist at Seacoast he was responsible for the final design of the Vernier Mini GC™ gas chromatograph, which is the first low-cost, compact chromatograph designed specifically for education. He also led development work of a monitor installed in vehicle to monitor alcohol impairment of the driver based on alcohol excreted through the driver’s hands.

Dr. Tolley earned his Bachelors of Science and Masters of Science Engineering in Metallurgical Engineering at the University of Utah, Salt Lake City and his Ph.D. in Organic Chemistry from Brigham Young University, Provo, UT. He has authored / co-authored 27 U.S. patents and over 75 peer-reviewed publications.

Prior to Seacoast Science, Dr. Tolley held a number of positions one where he was responsible for commercializing photon welding using conventional light sources to weld plastic parts. He has developed a novel calorimeter that allowed the measurement of thermodynamic properties and phase relations of supercritical fluids.

Dr. Tolley is a member of the American Chemical Society and in his 13th year as secretary to the San Diego Section.

Randy E. Jackson

Randy E. Jackson, Ph.D.

Research Scientist
Analytical Chemist

Dr. Jackson brings a broad and diverse analytical background. His primary area of focus is analysis methods for trace chemicals in blood samples using UV fluorescence and other techniques. His research includes the development of an analysis method for the cyanide metabolite 2-aminothiazoline-4-carboxylic acid (ATCA) and the development of the Cyanalyzer’s (cyanide exposure diagnostic) platform technology. Most of his research has had an emphasis on optimizing methods of analysis for CWAs.

Dr. Jackson is the inventor of the Cyanalyzer, a medical device that can detect trace concentration of cyanide in blood. It is currently undergoing advanced development by Seacoast in collaboration with South Dakota State University to produce a manufacturable instrument. Dr. Jackson's knowledge of biology, forensic science, and chemistry allows him to analyze problems from a unique perspective, aiding in the generation of innovative solutions to difficult problems.

Dr. Jackson earned his Bachelors of Science in Biology from Midwestern State University, a Master of Science in Forensic Science Sam Houston State University and his Ph. D. form South Dakota State University in Analytical Chemistry.

He has experience working as a laboratory Biologist. While at Saint-Gobain Vetrotex America he gained experience in Quality Control/Quality Assurance (QA/QC) and instrument calibration. Dr. Jacksond also has a number of years of forensic experience, he interned at the Montgomery County (Texas) Sheriff’s Office, where he gained experience in chain of custody and evidence preservation, as well as Good Laboratory Practices (GLP). He has also work on the detection an analysis of analytes of interest in biological fluids.
