Joan Oppenheimer, BCES

Joan OppenheimerMy name is Joan Oppenheimer, and it is a privilege to be considered as a candidate for Trustee-at-Large. This introductory statement briefly summarizes my 40-year career in environmental engineering and why I am interested in serving the Academy in this capacity.

I am a Board-Certified Environmental Scientist and a principal environmental consultant with Stantec. My interest in science began while attending the Bronx High School of Science in New York City. I chose not to pursue an engineering degree at Princeton University and obtained a BA in chemistry from Brandeis University and a MSPH at the University of North Carolina at Chapel Hill.  This probably explains why I became a chemist supporting engineering projects protective of public health. I’ve worked on many interesting projects, such as evaluating solids retention time impacts on pharmaceuticals and personal care products during biological treatment and generation of the data supporting the Surface Water Treatment Rule requirements for inactivation of Giardia cysts and Cryptosporidium oocysts in drinking water.

My tenure in the Academy began in 2012 when certification expanded to include environmental scientists. I am on the Membership Committee, the Nominating Committee, and Chairman of the Environmental Chemistry Committee. The Academy is an excellent resource for the environmental engineering and science community that provides its members with many opportunities to promote and demonstrate excellence, expertise, education, and engagement in their respective fields. Serving as a Trustee-at-Large will allow me to further contribute toward the continued success of the Academy.  

Yuefeng Xie, Ph.D., P.E., BCEE

Yuefeng XieI have been a dedicated member of AAEES since 2001. As a professor at Penn State, I have contributed significantly to both academia and the water industry. I have served as a member of the USEPA Science Advisory Board’s Drinking Committees across three administrations, chaired the AWWA Organic Contaminant Control Committee, and led the Southeastern Pennsylvania Section of the ACS as its Chair.

I have played a pivotal role in the water industry, particularly through my leadership at the Environmental Training Center at Penn State. Under my guidance, the center has provided training to over 15,000 water professionals (registrations). I have organized more than 20 professional workshops for ACS, AWWA, and other professional organizations. Furthermore, my involvement in water professional training extends internationally to Canada, Singapore, and China.

My achievements include being recognized as a Fulbright Scholar and a Fellow of the International Water Association. In 2023, I was honored to receive the AAEES Excellence in Environmental Engineering and Science Education award. I was awarded the Penn State University-wide Faculty Outreach award and nominated for an honorary road, “Xie Lane.” Notably, my advocacy led to the establishment of “Water Doc Lane” at Penn State University Park campus, serving as a tribute to all water professionals.

I am deeply committed to advancing environmental sustainability and fostering stronger connections between engineering education and environmental practice. It would be a privilege to serve as an AAEES trustee-at-large, leveraging my diverse experiences to further the mission of AAEES.

Only Board Certified Environmental Engineers (BCEE), Board Certified Environmental Engineering Members (BCEEM), Board Certified Environmental Scientists (BCES), and AAEES Members who are current on their dues are eligible to vote in the Officer Elections.   Honorary Members and Student Members are not eligible to vote in this election.  Click the button below to access the ballot.
