### Penetrating the Fog, Lifting the Veil from Algorithms

In 2005, Homer Walker received the WPI Board of Trustees’ Award for Outstanding Research and Creative Scholarship. His research and teaching interests include, among other things, computational and applied mathematics. He is internationally known for his role in the analysis and development of algorithms for computing solutions of systems of linear and nonlinear equations.

### Investigating the Relationship Between Fractal Geometry and Energy

Umberto Mosco says that the relationships between shape and sound and shape and color have always fascinated him. In fact, they have guided his life’s work. A world-renowned expert in mathematical analysis, he uses these simple terms to illustrate the complex mathematics that describe the relationship between an object’s geometry and energy.

### Breathing New Life into Materials

Having pioneered the field of optimal material design, Konstantin Lurie is shaking up the materials world again. He wants the world to begin to think of materials in a new way. Instead of substances with constant properties, he has shown that materials can be entities whose properties can change—in space as well as time.

### Useless Math

Sensor networks are made up of devices with the tiny processors and meager power supplies, which limit their ability to run the strong cryptosystems that are used to protect data in more robust computing environments. William Martin has drawn on mathematical systems that were once thought to have no practical use to help make public key cryptography run effectively on such devices.

### Better Prediction of Heart Attacks and Strokes

Without warning, arterial plaques can rupture, releasing debris and blood clots that can cause heart attacks or stroke. Large plaques can be removed, but Dalin Tang, professor of mathematical sciences and biomedical engineering, says the surgery may be over-prescribed. He has made it his life's work to develop tools to predict which plaques are likely to rupture.

### Using Matroid and Graph Theory for Diverse Applications

Brigitte Servatius is a discrete, or finite, mathematician, and her major tools are matroid and graph theory. Matroid theory is essential in developing and speeding up algorithms that are used to power the Internet and implement GPS tracking technology, among other applications.
