Dr. Allen was born and reared in Oakland, Maine, has four younger sisters, and has lived in Nevada, Massachusetts, Tennessee, Northern California, New Mexico, Southern California, and Hawaii. He has been to all 50 U.S. states, and has traveled internationally to Mexico, Canada, England, Singapore, Brazil, and the Dominican Republic. Prior to joining the Liberty faculty in 2013, he worked in private industry for 15 years on a variety of projects including the development of sensors for chemical warfare agents, integration of sensor networks for homeland security threat detection, and most recently, the conversion of algae to biofuels for the Department of Defense. He also developed covert and overt chemical markers and taggants for deterring fraud, counterfeiting, and product diversion and taught analytical chemistry at the University of New Mexico. Although his work in industry and academia was very interesting and exciting, his growing desire was to use his expertise in chemistry combined with his faith in a way that would impact God's kingdom, and to work in an environment, like Liberty, where he had the freedom to integrate God's Word into everyday learning. Other interests include praying for and supporting missionaries and studying end-times prophecy. Dr. Allen and his wife have three children who are homeschooled. Dr. Allen enjoys playing basketball and beach volleyball.


Algae can be grown to have a high protein and/or lipid content, which can be used for animal feed, biofuel, or both. Dr. Allen's group uses GC/MS/FID (Gas Chromatography coupled with Mass Spectrometric Detection and Flame Ionization Detection) for quantifying the total lipid content in samples obtained from algae biofuels companies. Several companies are researching cost-effective ways to optimize growth and harvesting techniques in an effort to convert the lipid fraction of the algae biomass into various types of company, can be used for improving the production and harvesting techniques.

This work provides students with hands-on, real-world, interdisciplinary training in both chemistry and biology, and provides them with valuable, transferrable skills and knowledge that prepares them for employment, graduate research, or medical school. For example, (1) students will apply fundamental principles of nutrient limitation, stoichiometry, kinetics, and equilibrium learned in their chemistry and biology courses to the preparation and analysis of samples. (2) Students will acquire valuable chemistry and biology research experience through literature searches, in sample/standard preparation techniques, in the use of state-of-the-art instrumentation, as well as in data analysis, interpretation, and reporting. (3) Students will learn how to effectively summarize and communicate scientific information.
