    Tarek Anous, a formerundergraduate student, who worked at the Wilson Lab with Professor Rich Galik on instrumentation for the International Linear Collider (ILC). The ILC is a proposed next-generation particle accelerator with a target date of 2015 to begin operation. Tarek helped construct a small detector that uses cosmic rays in order to simulate the real detector that will be used in the ILC. Cosmic rays hit the scintillator (a plastic rod) and produce photons whose signals ... read more ||

    Dionysios Anninos was recently an undergraduate physics major at Cornell. "The range of possibilities offered at Cornell is overwhelming. One can end up studying the most disparate fields and end up well versed in them. Personally, I tried to exploit this feature to the maximum. I ended up learning a lot of great physics by sampling a large set of physics courses offered at a unique level, as well as exploring economics and mathematics." "Furthermore, through its advanced courses and research opportunities, Cornell offers the student a unique ... read more ||

    Wui Ip Professor Carl Franck and student Wui Ip (who is at Cornell as part of the NSF's Research Experiences for Undergraduates program) are studying how cells interact and signal each other to form complicated structures. For example, cells communicate when conditions are good, and they exchange growth factors. Franck and Ip are focusing on the question "Why do cells need company to grow?" It is well known that a minimum culture is needed to grow cells. What determines that ... read more ||

    Peter Wittich is an assistant professor in LEPP. He collaborates with assistant professor Julia Thom's research group. They are part of an international collaboration preparing the Compact Muon Solenoid (CMS) experiment that will operate at the Large Hadron Collider (LHC) scheduled to begin operation in 2007 in Geneva, Switzerland. Professor Wittich explains that "We're trying to understand fundamental questions such as 'What is the nature of space-time?' and 'Where does mass come from?' We do this by smashing protons together and looking at the very small particles that come out ... read more ||
