good2 Dr. Amy Mueller – Principle Investigator

Dr. Mueller is an Assistant Professor at Northeastern University in the departments of Civil & Environmental Engineering and Marine & Environmental Sciences.  Work in the Environmental Sensors Lab builds on Dr. Mueller’s prior research at MIT’s Parsons Laboratory for Environmental Science and Engineering and the University of Washington’s Department of Oceanography.



jtc Jonathan Chihoski – Ph.D. Candidate (Civil Engineering)

Jonathan came to Northeastern via Georgia Tech and UMass Amherst where he studied Mechanical and Environmental Engineering.  Jonathan’s graduate work focuses on sensing systems for nutrients, particularly those related to issues of resource recovery and surface water quality/eutrophication.



WenjinWenjin Zhang – Ph.D. Candidate (Interdisciplinary Engineering)

Wenjin joined the group after completing her MS in Civil and Environmental Engineering.  Wenjin’s research focuses on informatics for decision and control of civil and environmental infrastructure systems, including machine learning applied to wastewater treatment sensing and process control.




Alfred Navato – Ph.D Candidate (Computer Engineering)

Alfred came to Northeastern from almost 8 years working in industry to tackle issues at the intersection of data methods and civil and environmental engineering, particularly focused on water resources.



Josh Toby – Class of 2021, Computer Engineering

Josh is tackling implementation of the embedded controller for a portable miniaturized microscope for on-site drinking water monitoring, including hardware control (lighting, sample slide movement) and data management (image collection, saving, and interfacing with automated microbial count algorithms).

Jahaan Saini – Class of 2021, Engineering

Jahaan is exploring questions around the mechanics of low-cost underwater releases, studying heat transfer and power consumption in a variety of melting and breaking architectures.  This contributes to next generation design for trace metal clean water sampling.

Paul Yi – Class of 2020, Environmental Engineering

Paul’s 3rd year undergraduate research utilizes lab analyses of wastewater treatment to contribute to the study of novel wastewater treatment (and resource recovery) processes.


Fizzah Shaikh – Class of 2021, Electrical and Computer Engineering

Fizzah dove into research at Northeastern in her very first year on campus, teaming up with Alex on embedded controller design where she has focused on data and time management as well as algorithm development. In her second year Fizzah tackled the challenges of drinking water quality monitoring in collaboration with Prof. Ameet Pinto’s lab, working on development of a portable “smart” microscope for automated real-time evaluation of water samples for microbial contamination.

Previous Lab Members

Version 2Anna Cullen – Class of 2020, Chemistry

Anna joined the lab in Fall 2016 to study issues related to farming productivity in developing countries.  Specifically Anna is working on a fast, cheap, point-of-sale test for fertilizer quality to protect career farmers from the economically-devastating consequences of purchasing low-quality fertilizers.



Alex Agudelo – Class of 2018, Electrical and Computer Engineering

Alex joined the team during his Junior year at Northeastern to lead development of an embedded controller for the trace-metal in-situ sampler which will be used to study nutrients (like Fe) at long-term ocean monitoring stations; this project integrates sensing, algorithm development, and controls.
