About Me - Versonnen

Introduction

Hello, my name is Hans-Nikolai Vießmann, and I am a computer scientist. Since 2015, I have been working on my PhD in Robotics and Autonomous Systems as part of a joint degree between the University of Edinburgh and Heriot-Watt University. My research interests include Functional Programming, GPGPUs, and Data Streaming to Accelerators. I am a driven and disciplined young individual who enjoys working on, around, and with computers.

Here are some things about me:

I am German
I enjoy going to the cinema
I love riding my bicycle
I love heavy metal
I love food & spirits

Education

September 2015 - Present: PhD Candidate

Heriot-Watt University & University of Edinburgh, Edinburgh, UK and Radboud University, Nijmegen, NL.

Topic: My research focuses on resolving challanges in translating a high-level programming language to GPGPU code using code-generation techniques in the context of a optimising compiler.

I am supervised by Sven-Bodo Scholz, as part of the Single-Assignment C research group with members of the HλperLab.
Initial funding provided by Engineering and Physical Sciences Research Council CDT initative through the Edinburgh Centre for Robotics, later funding provided by Radboud University through the Institute for Computing and Information Sciences.

Programme is a joint/double degree from three institutions.

Skills

Web Development

I have created several websites, or have helped create websites. Most were personal in nature, or as part of a project. I have also helped create a web page for a business as well (TECHFIX). I am a capable HTML, CSS, JavaScript, PHP, and Ruby developer.

Teamwork & Communication

I have been part of many group based projects. Some of these projects were think-tank style operations with no resulting final product. Others included extensive design and prototyping phases with several amendments and alterations to a final product.

Programming & Software Engineering

I am proficient in several programming languages including C, C++, Java, PHP, bash/zsh, etc. I am very familiar with various data-strucutres and patterns. Aditionally I have been specialising in multi-threaded development and associated aspects.

Network Design & Engineering

Good understanding of major networking protocols and their basic functionality, such as TCP, UDP, IP, SSH, DNS, etc.. I have used or use these and more protocols on a daily basis.

Time Management & Organization

I have a strict sense of duty and find myself obligated to completing an assignment to the best of my capabilities within the times given. I try my best to be as organized as possible.

Advanced IT/Server Usage

I have a good deal of experience in using not just Windows but a variety of *nix based operating systems as well. I am very good with the *nix terminal and its associated programs. I run several servers each with different functions (backup, web-hosting, VPN, etc.).
