Clients turn to Rica for her expertise in chemical fingerprinting using positive matrix factorization (PMF) to identify and quantify sources of contamination, especially in industrial areas. She also supports litigation by fusing PMF with advanced modeling and data science to craft accurate, robust, and defensible narratives from complex data sets.

In service to her field, Rica regularly presents at conferences and publishes her work in journals including the Journal of Marine Science, Journal of Atmospheric Sciences, and Environmental Science & Technology. Rica serves in the leadership of the Environmental Science & Technology and the Enforcement & Litigation committees within the American Bar Association’s Section of Environment, Energy, and Resources. Beyond her technical and leadership roles, Rica is committed to fostering inclusivity within the environmental consulting profession. She is on Geosyntec's Diversity Council, where she focuses on initiatives to make the firm more inclusive and diverse.
