--Last update:

Most of my courses are undergraduate computer science and mathematics courses.

Fall 2014 news

Recently, I am in the process of designing an undergraduate curriculum on cybersecurity. In Spring 2015, I will offer a course on gray-hat hacking. It will cover the basics of hacking ethics, laws concerning hacking, and obviously various exploit techniques. The purpose of this course is to help students understand the techniques potential attackers might employ; therefore they can design software and networks that are safer.

If you are interested in this course, shoot me an email. The pre-requisite is some prior programming experience, such as CS121 or IS370.

Here is a list of courses that I have taught over the years. If you are interested in any of the courses I have taught, just email me and I would be happy to send you more information.

My research interest is primarily the application of machine learning algorithms in data analysis. In particular, I am very interested in statistics based learning algorithms. For a list of my most current publications, please refer to my CV

Current projects (fall 14 and spring 15)

  • Sensor data classification. I am lookinging into how to classify noisy sensor data using machine learning algorithms. The goal is to provide relatively accurate position data of moving objects.
  • I am investigating how to design semi-supervised learning algorithms to detect the anomalies in network traffic, If you are an undergraduate in computer science or information systems, and is interested in this project, please contact me.
  • I am also working with a computer science senior on comparing feature selection and feature extraction approaches. We have finished coding a general neural network and selected a image database (MNIST from NYU). The simulation is underway to compare the behaviour of Fisher Discriminant Ratio and Singular Vector Decompositions.
  • Some useful links

I am big fan of DIY and enjoys a good joke.

More to come soon.
