Dr.-Ing. Erik Buchmann is head of the Young Investigator Group Privacy Awareness in Information Systems and its Implications on Society at the Institut für Programmstrukturen und Datenorganisation (IPD), Karlsruhe Institute of Technology.

Short CV

Erik Buchmann was born in Magdeburg, Germany in 1976. He received his Diploma (M.Sc.) in Business Informatics from the Otto-von-Guericke-University of Magdeburg, Germany in 2002. In 2006, he earned his Ph.D. in Computer Science (summa cum laude) from the same university. Since September 2006, Erik Buchmann is a research associate of the IPD, Karlsruhe Institute of Technology. By 2007, he became head of the Young Investigator Group Privacy Awareness in Information Systems and its Implications on Society. At this moment, Erik Buchmann is a visiting researcher and a representative of the database chair at Saarland University. His research interests include management and query processing of any kinds of imprecise, individual-related, large-volume data sets, e.g., from wireless sensor networks, location-based systems or smart-grid installations. Erik Buchmann is particularly interested in interdisciplinary work.

Recent Activities

Personal Stuff (in German)

  • Long, long years ago, i had the time to toy with semiconductors and microcontrollers. Here is a copy of my microcontroller-page which describes how to interface an Atmel 89Cx051, and how to connect peripherals like I2C bus devices, LC displays, stepper motors etc. Die Microcontroller-Seite (in German). Please note that the page is out of date. I do not have the time to update it, or to answer questions regarding microcontrollers.
