Anja Diet­rich stud­ied biol­o­gy at the Uni­ver­si­ty of Leipzig and is spe­cial­ized in the field of neu­ro­bi­ol­o­gy. Her PhD project focused on eat­ing-relat­ed bevav­iour­al con­trol. She exam­ines poten­tial dif­fer­ences between groups, dif­fer­ing in Body mass index (BMI) and mea­sures of eat­ing behav­iour using behav­iour­al tests and Func­tion­al mag­net­ic res­o­nance imag­ing (fMRI). In par­tic­u­lar She inves­ti­gates if there are vari­a­tions in brain activ­i­ty relat­ed to crav­ing and down-reg­u­la­tion of the desire for high-caloric food by means of fMRI. Fur­ther, she is inter­est­ed in poten­tial dif­fer­ences regard­ing the bal­ance between habit­u­al and goal-direct­ed behav­iour­al con­trol between groups based on BMI and mea­sures of eat­ing behav­iour using tests inves­ti­gat­ing instru­men­tal per­for­mance.
