West Sacramento, California

Andrew has experience performing freshwater fisheries assessments using common capture techniques, age/growth sampling, diet composition, water quality sampling, and laboratory analysis. He was a fisheries observer in the North Atlantic on both scallop and groundfish commercial fishing vessels, as well as an observer for marine mammals. His training allowed him to observe on vessels that fished using several gear types, including dredge, mid-water/bottom trawl, gillnet, rod and reel, and longline. He spent over 300 days at sea collecting extensive biological data pertaining to targeted catch, bycatch, environmental factors, as well as fishing effort and behavior. He is currently working to develop robust code to help automatically detect, enumerate, and classify organisms from images in order to automate processes and efficiently produce quantitative metrics from fisheries surveys.

Zack DeLuca is a fluvial geomorphologist with experience incorporating geologic insights into a variety of complex multidisciplinary projects. He is focused on systems thinking approaches to geomorphic questions that combine surficial geology, local land-use history, sediment connectivity, and hydrology. Zack has completed geomorphic assessments, field surveys, and built complex 1D and 2D hydraulic models in HEC-RAS.  He has experience using geographic information systems (GIS) and Python for geomorphic and hydrologic analyses and cartography. Zack received his M.S. in Geoscience with an emphasis on fluvial geomorphology from the University of Montana. His thesis evaluated the geomorphic response to extreme flooding in Northern Yellowstone National Park using a combination of rapid assessments, analysis of high-resolution topography data, and hydraulic modeling to reconstruct flood conditions, estimate flood forces and sediment transport potential, and quantify geomorphic change following flooding.
