Dr. Carlos Letelier Gordo
1st Vice President

Dr. Carlos Letelier Gordo is an aquacultural engineer from Universidad Católica del Norte (UCN) Chile, where he worked at the Applied Aquaculture Engineering unit designing marine culture centers and recirculating marine aquaculture systems. Posteriorly he obtained the M.Sc. Eng. degree in Civil Environmental Engineering at the Technical University of Denmark (DTU). His study line focused on residual resources engineering, participating in the Bioenergy group on biogas production and biological treatment of aquaculture effluent. Subsequently he obtained a Ph.D. degree from DTU Aqua based on his doctoral thesis entitled “Transforming waste into new resources: optimizing sludge hydrolysis to improve nitrogen removal in aquaculture through denitrification”. Presently, he is a Postdoc at DTU Aqua working on the end-of-pipe treatment of marine land-based recirculation systems and freshwater systems with focus on denitrification, phosphorous removal, biogas production, H2S production and aquaponics.

Tim Pfeiffer, Ph.D.
Secretary/Treasurer

Dr. Pfeiffer obtained his doctorate degree from Louisiana State University in Engineering Science from the Department of Biological and Agricultural Engineering. Dr. Pfeiffer worked for the USDA as an Agricultural Engineer specializing in aquaculture engineering for over 13 years with a majority of his time spent at the Harbor Branch Oceanographic Institute in Fort Pierce, FL. While with USDA he specialized in design and research of recirculating aquaculture systems, effluent management, and energy and water conservation for RAS designs. Project funding for the USDA research was terminated in 2011 and Dr. Pfeiffer then worked with the Foreign Agricultural Service branch of USDA as an Agricultural Advisor in Afghanistan. He was stationed in Afghanistan for over a year and his main focus was water resource development and conservation. Upon his return in 2013 he began working for Aquaculture System Technology. He is the Research Director for the Engineering department at AST and also assists in system design for the initial phases of a project. Dr. Pfeiffer has been a long-time member of AES (18 yrs) and has served as its Secretary/Treasurer from 2006 until 2012. He currently serves on the editorial board of the Aquaculture Engineering journal.

Mark Schumann
Director

Mark Schumann studied biology from 2004 to 2010 with a focus in fish ecology and limnology and holds a diploma degree from the University of Konstanz in Baden-Württemberg, Germany. His research at the Fisheries Research Station of Baden-Württemberg in Langenargen, where he has worked since 2010, is focused on impact of feed composition on aquaculture effluents, which is also topic of his doctoral theses. Further research fields are suspended solids in recirculating aquaculture systems and fish welfare. He is in charge of running and developing the research RAS facilities and leads the aquaculture team.

Lauren Jescovitch
Director

Lauren Jescovitch is a Research Associate at Michigan State University (MSU) and a Distance Learning Course Designer for Auburn University. At MSU, Lauren is studying automated analysis of student reasoning in STEM (science, technology, engineering, and mathematics). As a course designer, Lauren is redesigning online courses for a certificate of aquaculture professionals. She earned her Ph.D. and Masters in Fisheries and Allied Aquaculture at Auburn University, and her Bachelors in Fisheries Biology and Environmental Science at Mansfield University. She has been involved in a number of aquaculture research projects in the last 10 years of which include water quality and RAS systems at The Conservation Fund’s Freshwater Institute, GIS application for a proposed pond land-to-water surface area ratio, and water quality and split-pond design, coastal ecosystems, and shrimp growth. Lauren is the chair of the student subunit committee for the US Aquaculture Society (USAS) and was the first president and founder of the Auburn University USAS student subunit.

Paulo Mira Fernandes
Director, International

Dr. Fernandes earned a B.Sc. in Marine Biology from the Algarve University, spent one year in Wageningen University during a M.Sc. in Aquaculture and Fisheries and has worked within aquaculture in both Italy and Wales. During his Ph.D. at the Technical University of Denmark (DTU Aqua, Section for Aquacutlure), he studied particle accumulation in recirculation systems and how it affected fish and system performance. He spent one more year in Denmark after his Ph.D. assessing new and existing methods for effluent treatment in seawater recirculation systems.

As of November 2016, Paulo has been working as a researcher at the Skretting Aquaculture Research Center (ARC). His main research focus is to further progress already existing recirculation diets, while also developing technical solutions and establishing standard for salmonid rearing in recirculating aquaculture systems. In general, he is interested in the impact of nutrition on fish performance, water treatment efficiency and how it, retroactively, affects fish performance. At the same time, he supports Skretting operating companies and Skretting ARC research stations around the world and their customers in terms of best practices for aquaculture operation and water quality management.
