+    |I’m a Professor of Software Technology in the Department of       |
+    |Information and Computing Sciences. My research focuses on how    |
+    |programming languages can be used to improve the quality of       |
+    |software. Conventional software testing is very important, but    |
+    |can’t guarantee the absence of errors. We are addressing this     |
+    |problem in our research on developing and using programming       |
+    |languages that are based on mathematical theory, so we can prove  |
+    |that a program will work in all scenarios. We call it             |
+    |‘correctness by construction’. The real world significance is     |
+    |obvious: it saves a lot of time and it eliminates errors so which |
+    |company wouldn’t want it?                                         |
