I am a professor of computer science at Friedrich-Alexander-Universität Erlangen-Nürnberg. In my prior life my research focus for a long time was on fault-tolerant distributed algorithms. Today I focus on computer security and forensic computing. Since I work in the area of applied computer security I am constantly trying to cover my traces: From 2002 to 2010 I worked at five different universities under two different names.

I don’t have any account in social media, so any account with my name is probably somebody else’s.

I support The Cost of Knowledge and currently refrain from reviewing and editorial services to Elsevier.

My ORCID is 0000-0002-8279-8401.

Announcements

My Sprechstunde during summer semester 2022 is Mondays between 16:00 and 17:00. Please indicate in advance to Christine Stief if you plan to come.

Official Short Biography

Felix Freiling is full professor of Computer Science at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) in Germany. His main research focus is on forensic computing, meaning the application of methods from computer science to answer questions of the legal system. He has published numerous papers on the methodological foundations of the field, including acquisition processes of digital evidence, tool support for analysis of digital evidence, and technical aspects of legal admissability. He is one of the founders of the first German professional Bachelors and Masters degree programmes focussing on digital forensics and has trained several generations of expert witnesses therein. He is also the spokesperson of the Research Training Group “Cybercrime and Forensic Computing” funded by Deutsche Forschungsgemeinschaft.

Felix Freiling’s Email Policy

On December 18, 2008 the number of unanswered messages in my email inbox surpassed 1000. I surrender! On christmas day 2008 I decided to change my email handling policy: In the future, I will treat emails more like I treat telephone calls. I will fix a time interval d and after d time I will completely remove all unanswered email from my inbox that is older than d. This means I will most probably not respond anymore to emails that have not been answered in d time. Currently d is one year, but it may be adjusted. I apologize for any inconvenience this may cause, but I am now convinced that I cannot continue to treat email the same as I treat postal mail. If you need a definitive response from me within a certain time, it is probably more reliable to send a letter by postal mail.

Update in April 2009: d is now 6 months.

Update in July 2009: d is now 2 months.

Update in December 2010: d is now 3 weeks.

Update in January 2012: d is now 1 week

Update in December 2013: d is now 4 days.

Update in December 2014: d is now 2 days.

Update in September 2017: d is now 3 days.

Exams

Students planning an oral examination have the chance to visit such an exam as an observer (Hospitation) beforehand under the condition that they do not disturb the exam and the examined student agrees.

Internship and Employment Opportunities

My lab infrequently offers internships and short or long term employment to interested and well-qualified candidates. I however only reply to normal postal mail or (sometimes) to email which has been sent individually to me. In case you wish to communicate via email and are looking for an internship, please include the code word “ref: nightingale” in the subject of your mail to prove that you prepared an individual email.
