Virginia Tech Department of Biological Systems Engineering Location: Northern Virginia, Washington, D.C. metropolitan area
Position Overview
Dr. Zhiwu (Drew) Wang’s research team at Virginia Tech invites applications for a postdoctoral position focused on developing and demonstrating wastewater treatment technologies through pilot- and full-scale testing at operating treatment facilities. The successful candidate will work closely with municipal utilities, consulting engineers, and industry partners to translate research into practical improvements in treatment performance. The position is based in Northern Virginia from the beginning of the appointment. The initial appointment is for one year, with potential renewal based on performance and funding availability. Candidates available to begin promptly are encouraged to apply.
Research Focus
- Hydrocyclone-enabled sludge densification: Evaluate and optimize hydrocyclone selection and operation to improve sludge characteristics, settleability, and treatment performance.
- Partial denitrification–anammox (PdNA): Develop and optimize biological nitrogen removal processes through pilot- and full-scale testing with real wastewater.
Key Responsibilities
- Design, conduct, and troubleshoot laboratory, pilot, and full-scale experiments addressing practical wastewater treatment challenges.
- Coordinate field activities with plant operators, engineers, and project partners while maintaining safe and reliable research operations.
- Analyze experimental and operational data, prepare technical reports, and publish high-quality peer-reviewed journal articles.
- Communicate findings to utility and industry audiences and contribute to project management, student mentoring, and proposal development.
Qualifications
- A Ph.D. in Environmental Engineering, Civil Engineering, Biological Systems Engineering, Chemical Engineering, or a closely related field by the appointment start date.
- Relevant research experience in biological wastewater treatment, sludge densification and settleability, activated sludge systems, biological nitrogen removal, anammox, or related processes.
- Demonstrated scientific writing ability and a strong record of peer-reviewed publications.
- Strong experimental, analytical, and troubleshooting skills, with the ability to work independently and bring projects to completion.
- Excellent interpersonal skills and a collaborative working style. Candidates must communicate effectively with operators, engineers, industry representatives, and academic colleagues; coordinate competing priorities; and build productive professional relationships.
- Willingness to conduct hands-on fieldwork involving real wastewater and treatment equipment.
- A valid driver’s license, a personal vehicle, and the ability to safely drive cars and trucks used for project activities.
Experience with pilot- or full-scale treatment systems and direct collaboration with wastewater utilities or industry partners is strongly preferred.
