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.

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.

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.

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.

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.

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.

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.

Henri Seppänen
Guest researcher (MSc)
Developing and studying, e.g., the main tether of the ESAIL.
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.
