Greger Thornell
Assoc. Prof., Director

I direct the ÅSTC, and manage and participate in several of its research projects. My background includes Materials Physics to the MSc and PhD degree, and Engineering Physics specializing in Microsystems Technology to the level of Assoc. Prof. Since 1994, I have worked with various aspects of microtechnology – starting with materials and process technology, proceeding with basic devices and now engaging with whole systems. Outside academia, but partly in parallel with the university career, I have worked as a project manager in R&D, as VP Operations, and as the CTO of a company in the field of electronics and frequency control based on quartz crystal oscillators., phone: +46-18-471 7126

Hugo Nguyen
Assoc. Prof.
Supervisor in Microsystem Technology
Senior Lecturer in Machine Engineering

I am engaged in the SDTM project as manager, supervisor and senior researcher. The project aims to develop a SDT-magnetometer for space use.
DADU – Deeper Access Deeper Understanding is another project I am involved in. I take the responsibility for development of the miniaturized submersible vehicle and interface with micro-subsystems.
Through the years at ÅSTC, I participated actively as researcher in many projects relating to nanosatellites, such as the NanoSpace-1 satellite, LOVEcraft, Earth Intelligent Surveillance, Multifunctional Micro- and Nano-system, and MacoSphere – A hydrogen storage system, etc.
I have been teaching various engineering courses at Uppsala University since 1996 and still enjoy the part-time lecturing., phone: +46-18-471 6838

Anders Persson
Ass. Prof.

I’m engaged in the SDTM project, researching the applicability of magnetoresistive technology to spaceborne magnetometers. I am currently working with the manufacturing and characterization of the magnetometers sensor elements. I am also involved in supervising diploma students within the project. I graduated from the Master of Science in Engineering Physics program in 2007, where I specialized in space technology, and have a solid background in space physics, electronics and electromagnetism. In continuation of my research, I am also interested in the applications of electromagnetic sensors in space in general, and to radio astronomy, and satellite communications in particular., phone: +46-18-471 3111

Fredric Eriksson
Assoc. Prof.

I am currently working in a project on High Temperature Materials for MEMS (HTM-MEMS), where the aim is to find possible materials solutions for MEMS in high temperature and harsh environments. My background includes a MSc in Engineering Physics and a PhD degree in Materials Science. My main interests are material properties and analytical techniques in Materials Science., phone: +46-18-471 3090

Kristoffer Palmer
MSc, PhD student

Currently, I’m engaged in the reflectarray antenna project where I’m studying the possibility of scaling down microwave reflectarray antennas to optical and infrared frequencies, the OCOM project where I’m fabricating an actuator for laser beam-steering and in the micropropulsion project where I currently design a gasflow sensor. Prior to my PhD-position, I was a Master of Science student here in Uppsala where I specialized in space technology. In my diploma work I described the utilization of orbital angular momentum of electromagnetic radiation in the radio domain. Among other things I’m interested in satellite communications and exploration of our solar system., phone: +46-18-471 5859

Jonas Jonsson
MSc, PhD student

I am involved in the development, manufacturing and testing of a miniaturized submarine, by using MEMS technology. I am also involved in the MST1 course, where I am running the laboratory exercises. My background is in space engineering, with a specialization in spacecraft and electrical engineering, and in engineering physics, with a focus on space physics. As part of my thesis I worked with the Hydrothermal Vent Bio-sampler at NASA Jet Propulsion Laboratory, which was successfully tested off the coast of Iceland and later Japan, at deep-sea hydrothermal vent systems. My main interest is in the development and construction of systems for the exploration of extreme environments, here on Earth and beyond., phone: +46-18-471 7235

Ville Lekholm
MSc, PhD student

I am studying microrocket jets using schlieren imaging techniques to determine whether and how the shape and symmetry of the expansion cone affects the performance of the rocket chip.

Martin Berglund
MSc, PhD student

I am developing a diffractive optical element that will, through projection of a laser pattern, give perspective in pictures captured by the camera on board the DADU micro submarine.

Johan Sundqvist
Research assistant (MSc)

Having finished my diploma work designing, manufacturing and testing electronics for the sensor in the SDTM project, I now work with, among other things, the breadboard electronics for the OCOM system, and many issues in the DADU project, where system architecture and electronics for the propulsion modules are of primary concern., phone: +46-18-471 3114

Pär-Johan Oskarsson
MSc (former diploma worker)

I have done my Ms.c. thesis at ÅSTC where I simulated free space optical links between formation flying spacecraft. This has been a part of the preparatory work for ÅSTC's OCOM project. The goal has been to investigate link performance with respect to transmitter and receiver telescope apertures, transmitter optics, communication distance, receivers, modulation formats and pointing jitter caused by noise in the tracking system.
