Profile

Dur­ing his mas­ter the­sis at the Uni­ver­si­ty of Kon­stanz Hen­drik inves­ti­gat­ed the effect of train­ings inten­si­ty on short- and long-term mem­o­ry in hon­ey­bees. For his PhD he switched his focus on human neu­ro­sciences and start­ed work­ing in the O’Brain Lab in May 2017. Here he is inves­ti­gat­ing how obe­si­ty and dif­fer­ent styles of diet manip­u­late our brain, espe­cial­ly the dopamin­er­gic sys­tem. The main ques­tion is if diet itself already can change the way our brain works, our abil­i­ty to learn and han­dle cog­ni­tive tasks. For this pur­pose he is using behav­ioral test­ing and neu­roimag­ing and com­bine these with a genet­ic approach.
