Dr. Niezgoda is an Associate Professor of Civil Engineering at Gonzaga University and a registered licensed engineer in the state of Wyoming. She has an emphasis in water resources engineering and teaches and conducts research in the areas of engineering education, hydraulic engineering, river engineering/stream restoration, soil erosion and sediment transport, uncertainty and risk assessment, and porous pavement applications.

Dr. Niezgoda has developed a risk-benefit assessment method based on design failure modes and effects analysis for use in selecting streambank stabilization measures and improving the design of stream restoration projects.  She is actively working on two monitoring related research efforts: the development of an effectiveness monitoring protocol for urban stream restoration projects, and the effectiveness of beaver dam analogs and trapping sediment in watersheds.  Dr. Niezgoda is also actively involved in the ASCE Environmental and Water Resources Institute, holding officer positions in task committees under the Hydraulics and Waterways Council.  Working with members of the Stream Restoration Educational Materials Task Committee, Dr. Niezgoda has developed a stream restoration body of knowledge that synthesizes the state-of-the-art in stream restoration education requirements and sets the basis for developing a national certification. Dr. Niezgoda is also highly active in River Restoration Northwest (RRNW), and is currently an officer on the board of directors. RRNW is a non-profit organization which seeks to advance the science and standards of practice in river restoration through educational programs that emphasize a process based, interdisciplinary approach to restoration.  She has published numerous papers on a variety of river issues, including bridge scour, sediment transport, risk and uncertainty in stream restoration design, channel forming flow predictions, erodibility of cohesive channels, and the practice of stream restoration.
