dr. Andrei Hanu


Position: Principal Investigator

Institution: NASA’s Goddard Space Flight Center

Contact: andrei.hanu@nasa.gov and hanua@mcmaster.ca

Areas of Research:

  • CubeSats for space radiation dosimetry and particle tracking
  • Position sensitive radiation dosimeters for future deep space missions
  • Micro-pattern gas detectors for low mass space telescopes, particle tracking, medical imaging, and radiation dosimetry

Motivation: Space exploration is an ongoing adventure that captivates our imagination resulting in scientific and technological breakthroughs that benefit all of humanity. Currently, space programmes are shifting from government-driven strategies to commercial-driven initiatives with a common long term goal of sending humans to Mars and beyond. This means access to space is becoming cheaper and more frequent. However, one the biggest threats to any manned space exploration mission remains the harsh radiation environment and its health effects on astronauts. The NEUDOSE mission concept grew out of the need to developed advanced radiation dosimeters that lower the risk of deep space mission by providing superior radiation exposure monitoring. McMaster University is one of the world’s foremost institutions on health effects from radiation exposure and is ideally suited to address this challenge. NEUDOSE is the first of many CubeSat missions from McMaster University that will test advanced radiation monitoring technologies and train the next generation of Canadian scientists. This is a good time to like space!

ERICA DAO

Position: Project Manager & Web Master

Area of Study: Master's Student - Radiation Sciences (Medical Physics)

Member Since:  January 2015

Science/Engineering Interests: Compositional imaging of cancerous tissues using X-Ray Fluorescence (XRF) and Energy Dispersive X-Ray Diffraction (EDXRD), Measuring Iron in the skin using XRF as a surrogate marker for total body iron burden for diseases such as Beta Thalassemia

Motivation: Space travel is a growing field of research, and with the upcoming interest in human missions to Mars, the implications of this activity to human health must be known. As a student in medical physics, I've always had an interest in how radiation is utilized in medical practices and its effects on the human body. This new project combines my interests in dosimetry and health studies in one unique project!

ERIC JOHNSTON

Position: Systems Engineering Specialist

Area of Study: PhD Student - Radiation Sciences (Medical Physics)

Member Since:  January 2015

Science/Engineering Interests: My interests include detection of trace elements using Polarized Energy Dispersive X-Ray Fluorescence (Polarized EDXRF), compositional analysis of tissue samples using Energy Dispersive X-Ray Diffraction (EDXRD), and  designing and building a combination polarized EDXRF and EDXRD system for classifying diseased tissues. Other interests include radiation detector instrumentation design, machine learning for physics applications, and medical equipment design.

Motivation: I have always had an interest in space exploration and with recent developments trending towards the commercialization of space, the field is rapidly growing. I find the design constraints on engineering a space ready system intriguing, and I enjoy the challenge they provide.
