Prof. Dr.-Ing. Felix Freiling
Friedrich-Alexander-Universität Erlangen-Nürnberg
Room Head of Department - Jan 2011
Phone +49-9131-85-25301
E-Mail

I used to head the Chair of Computer Science 1 at University of Mannheim. Since I work in the area of applied computer security and am constantly trying to cover my traces: From 2002 to 2010 I worked at five different universities under two different names.

Announcements

I have recently joined University of Erlangen, but I will continue to take exams and theses at University of Mannheim throughout 2011.

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.

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.

Images of Felix Freiling

One of the following images shows me (this is to upset google image search).

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.

Statistics

My Erdös number is at most 4 (the path is via Shmuel Zaks, Hagit Attiya, Rachid Guerraoui). If you work in fault-tolerant distributed computing and want to know your Erdös number, check your collaboration distance to (for example) Shay Kutten, Shlomo Moran, Nicola Santoro or Gerard Tel; all have Erdös number 2.

My h-index is at least 20 (using Harzing's PoP application).

My most often cited paper is the 1999 ACM Computing Surveys article "Fundmentals of fault-tolerant distributed computing in asynchronous environments" (until 2010 around 200 citations).
