Postdoctoral Associate
Required Qualifications (as evidenced by an attached resume):
- Doctoral degree (or foreign equivalent) in Mechanical, Aerospace, Chemical, or Electrical Engineering, or a closely related field in hand by the start of the appointment.
- Hands-on experimental research with engines or combustion systems, including gaseous emissions measurement.
- Experience with data acquisition and analysis.
- A valid U.S. Driver's License.
Preferred Qualifications:
- Peer-reviewed publications and strong technical writing.
- Experience with hydrogen or ammonia combustion in research engine applications.
- Experience with control and integration systems, load banks, or electrical power measurement.
- Skilled in machining, fabrication, and wiring.
Brief Description of Duties:
The Postdoctoral Associate will conduct experimental research in the Advanced Combustion & Energy Systems Laboratory (ACES Lab) under the direction of Dr. Dimitris Assanis in the Department of Mechanical Engineering. The ACES Lab is an active engines laboratory operating highly instrumented single-cylinder research engines (Spark-Ignition CFR, Compression-Ignition Hydra, Fully Flexible Valvetrain Actuation Hydra, and Optical engine) on fuels including hydrogen, ammonia, and alcohols, with ignition systems ranging from laser ignition to pre-chambers, along with a 125 kW natural-gas engine genset.
The candidate will also lead the lab’s new mobile Performance & Emissions Validation Laboratory, the command center for independent validation of a 250 kW Mainspring Energy linear generator running on 100% hydrogen at National Grid’s Northport Power Plant. This NYSERDA-sponsored, multi-million-dollar, 12-month pilot with National Grid Ventures and the Long Island Power Authority (LIPA) is the first of its kind in New York State. This unique, high-visibility position, spanning early-TRL optical work through a late-TRL power-plant demonstration, lets one researcher lead a utility-scale demonstration while enabling publication of fundamental engine research in the same appointment.
The successful candidate will be self-sufficient, meticulous, and reliable, take pride in their work, and exercise strong organizational and time-management skills with an exceptional attention to detail. Essential for this role is the adeptness to work independently as well as part of a team, including extended test days and occasional overnight runs during field campaigns.
Duties:
Research:
- Conduct experiments on single-cylinder research engines fueled with hydrogen, ammonia, and alcohols, including novel ignition systems (laser ignition, pre-chambers).
- Participate/assist in manuscript writing for publication in scientific journals and conference papers from laboratory pilot results and/or make presentations at ASME, SAE, and Combustion Institute meetings.
- Contribute to proposals that build the laboratory’s next funded projects; mentor graduate and undergraduate researchers.
Technical:
- Commission the mobile command center on the laboratory engines through heated sample lines before it deploys and whenever it is required to return to campus; support its deployment to the Northport pilot and its subsequent redeployment to the HyPower renewable-hydrogen R&D testbed and other sponsored projects.
- Operate, maintain, and troubleshoot the analyzer suite: FTIR, chemiluminescence NOx (including a low-range ppb analyzer), FID for hydrocarbons, NDIR CO/CO₂, paramagnetic O₂, and a hydrogen analyzer (HORIBA HyEVO) or equivalent. Run zero/span calibrations, purges, leak checks, and drift checks; manage calibration-gas inventory and certificates.
- Maintain the heated sample system (heated probes, filters, and lines; pumps; switching valves for pre- and post-catalyst sampling) and apply standardized emissions measurement protocols and practices, documenting quality assurance for every test.
- Operate the control and integration systems that commands the linear generator and load bank to run defined load profiles (step functions, transients, cold and hot starts); logging data such as electrical outputs, fuel flow, and ambient conditions to calculate efficiency and response time, among a suite of other key performance metrics.
- Operate and maintain the National Instruments CompactDAQ and LabVIEW system, including analyzer communications over Modbus TCP/IP, valve control, acoustic channels, and the weather station; maintain networks, time synchronization, data backup, and chain of custody for all data.
- Execute approximately 12 test events over the 12-month pilot, each with about 2–3 weeks of preparation, a 24-hour full-load run or about 5 days of part-load testing, and 1–2 weeks of post-test calibration and data reduction.
- Follow and help write technical documentation, such as hydrogen and compressed-gas safety procedures for the command center, laboratory, and host site; coordinate the students and plant staff who support each field campaign.
Administrative:
- Reduce and analyze campaign data (emission indices, efficiency, transient behavior, seasonal trends); write technical reports for National Grid and NYSERDA; lead SBU’s sections of the final independent validation report; present at sponsor meetings.
- Other duties as assigned.
Senior Postdoctoral Associate:
Required Qualifications (as evidenced by an attached resume):
- Doctoral degree (or foreign equivalent) in Mechanical, Aerospace, Chemical, or Electrical Engineering, or a closely related field in hand by the start of the appointment.
- Three or more years of relevant research experience.
- Hands-on experimental research with engines or combustion systems, including gaseous emissions measurement.
- Experience with data acquisition and analysis.
- License to drive in the US.
Preferred Qualifications:
- Peer-reviewed publications and strong technical writing.
- Experience with hydrogen or ammonia combustion in research engine applications.
- Experience with control and integration systems, load banks, or electrical power measurement.
- Skilled in machining, fabrication, and wiring.
