I have been Pro­fes­sor for com­pu­ter sci­ence and head of the chair for usa­ble se­cu­ri­ty and pri­va­cy since April 2018. Pre­vious­ly, I was head of the in­for­ma­ti­on se­cu­ri­ty in­sti­tu­te at Leib­niz Uni­ver­si­ty in Han­no­ver (2017 - 2018). From 2016 to 2017 I was in­de­pen­dent re­se­arch group lea­der of the usa­ble se­cu­ri­ty and pri­va­cy group at CISPA, Saar­land Uni­ver­si­ty. I re­cei­ved a PhD in com­pu­ter sci­ence from Leib­niz Uni­ver­si­ty Han­no­ver in 2016. In 2015 I was soft­ware en­gi­neer (SWE) in­tern in the Chro­me Se­cu­ri­ty team at Goog­le in Moun­tain View.


Broad­ly, I study the in­ter­sec­tion of com­pu­ter se­cu­ri­ty and pri­va­cy with human fac­tors. I'm par­ti­cu­lar­ly in­te­rested in in­ves­ti­ga­ting end users, ad­mi­nis­tra­tors, de­ve­lo­pers and de­si­gners of com­pu­ter sys­tems and their in­ter­de­pen­den­cies with com­pu­ter se­cu­ri­ty and pri­va­cy me­cha­nis­ms. My re­se­arch in­vol­ves lar­ge-sca­le ana­ly­ses of the In­ter­net and soft­ware re­po­si­to­ries to un­der­stand the huge chal­len­ges hu­mans face when in­ter­ac­ting with com­pu­ter se­cu­ri­ty and pri­va­cy me­cha­nis­ms. To un­der­stand root cau­ses, eva­lua­te exis­ting me­cha­nis­ms and in­ves­ti­ga­te novel ideas, I con­duct all kinds of user stu­dies with end users, ad­mi­nis­tra­tors, and de­ve­lo­pers of these sys­tems.

I am re­ci­pi­ent of a Goog­le Fa­cul­ty Re­se­arch Award (2017), the John Karat Usa­ble Pri­va­cy and Se­cu­ri­ty Stu­dent Re­se­arch Award (2017) and the Heinz Mai­er-Leib­nitz-Pri­ze (2018). One of the pa­pers I co-aut­ho­red won the Best Sci­en­ti­fic Cy­ber­se­cu­ri­ty Paper Com­pe­ti­ti­on of the NSA (2016).

My re­se­arch is re­gu­lar­ly pu­blis­hed at top-tier ve­nues (e.g. Oak­land, CCS, USE­NIX Se­cu­ri­ty).

If you are in­te­rested in my work, wish to col­la­bo­ra­te with me, want to re­quest a de­tai­led CV or for wha­te­ver other re­a­son, plea­se do not he­si­ta­te to con­tact me.
