Undergraduate Research 
Undergraduate Research
There are many problems and projects in Algebraic Coding Theory that are accessible to undergraduates. In general, we combine algebraic theory with programming skills to search for new codes, codes with better parameters than currently best known codes. This is one of the main problems of coding theory. One of the interesting feature of the problem is that it can be approached from many different perspectives using a variety of tools, some very sophisticated (e.g. advanced algebraic geometry), some rather elementary (e.g. elementary but insightful search algorithms). If you are interested in doing research in this area I encourage you to contact me. Projects are available for beginners and experts. Below is a list of undergradute projects, papers and presentations produced by Kenyon students. Minimal background needed to get started is a course on Linear Algebra and some programming experience. Additionally, courses on Abstract Algebra, Combinatorics, and advanced programming (e.g. Data Structures) are highly recommended.
In addition to our active undergraduate research program with Kenyon students, I also mentor highly motivated and exceptionally strong international high school students for research in coding theory and cryptography offered by Pioneer Academics. This unique program connects talented high school students from all around the world with resources to conduct research. We have also published papers with Pioneer scholars such as this.
