About Arend J. Poelarends
Dr. Poelarends is an astrophysicist. He was born and raised in the Netherlands, in a small town surrounded by farms, rivers and dikes. You could always find him outside and this is where he developed a deep love for God's creation. He is still in awe with the beauty of creation (not only stars!) and likes to be outside whenever he can. He loves active sports like cycling, hiking, running, sailing, swimming, kite surfing, camping and backpacking. One of these years he hopes to do a triathlon. He lives with his wife and daughter in Wheaton.

Dr. Poelarends research focuses on the evolution of stars, specifically those between 8 and 10 times as massive as the sun, i.e. the transition zone between stars that evolve into a white dwarf and stars that explode as a supernova and form a neutron star. He is particularly interested in the later stages of their evolution, and uses computational modeling to study their pre-supernova evolution and chemical makeup. These stars could possibly be the birthplace of a significant fraction of the chemical elements in our galaxy (r-process elements), of which we don’t know their origin of yet.
In addition to numerical/theoretical research, Dr. Poelarends also uses the new Wheaton telescope to carry out meaningful astronomical observations of objects that are out of reach of amateur telescopes and not important enough for professional telescopes. Currently he focuses his efforts on the detection of exoplanets. This resulted in a very fruitful observing campaign during the summer of 2012, in which one of his undergraduate students detected several exoplanets. Possible future areas of research might also be variable stars and asteroids.
The last area of interest is the intersection of science and faith. Dr. Poelarends is particularly interested in the role of worldview stories, and how these shape our identity, our view of God and this reality, and our ethics.
