Jean Froment
Jean Froment is a researcher at the climate and research institute NILU.
Jean has conducted his PhD. at the Norwegian institute of Water Research (NIVA) and University of Oslo (UiO) focusing on Effect-Directed analysis (EDA). His post-doctoral experiences at the UFZ (Leipzig, Germany) and Stockholm University (Sweden) focused on performing nontarget analysis of biological and environmental samples.
Jean’s main research interests include the screening of environmental samples (particulate matter, water…) by chromatography (LC, or GC) coupled to high-resolution mass spectrometers (HRMS). Together with in vitro bioassays, nontarget analysis allows the detection of unexpected toxicants in the environment.
Jean is also passionate about the use of open-source software for the data processing of HRMS data and in silico tools to reveal the chemical composition and structure of unknown features.

Huy Duong Gia
Huy Duong Gia is currently a PHD-candidate at Stiftelsen NILU (since 2023).
He has a Bachelor degree in Control engineering and Automation (from 2015 to 2019 at Ho Chi Minh city University of Technology), in which he learned about control engineering, embedded systems, electronic design (PCB) and IoT application.
He then moved on to become an Embedded systems engineer (from 2019 to 2021 at BKASIC Technology cooperation). In 2 years as an engineer, he designed and programmed (C language) embedded system for electronic products, especially with high-speed signal devices. He used IoT application to control the product over internet, and designed hardware (PCB) for embedded system, control board, and high frequency PCB.
Huy then earned his master's degree in Micro and Nano System Technology (from 2021 to 2023 at University of South-eastern Norway). Here he went to the tiny world to study Nano and Micro system technology, especially Photonics devices, Optics, and MEMS (Mechanic-Electronic Micro System) design.
Now he is working under the MISO project. His main focus is on developing ambient monitors for greenhouse gases (GHGs) with low power consumption for long-term deployment in the Arctic and wetlands. By integrating tinyML (Tiny Machine Learning), he aims not only to improve the accuracy and reliability of data collected from these sensors but also to reduce power consumption for prolonged use. The goal is to make air quality data in the Arctic and wetlands more accessible, accurate, and useful for researchers and the general public.
