Mar­tin Feder­busch is study­ing med­i­cine. His grad­u­a­tion is planned for Decem­ber 2015. In Feb­ru­ary 2012 he found his way to the O’Brain Project through the fund­ing pro­gramme MD Pro 1of the Inte­grat­ed Research and Treat­ment Cen­ter (IFB) Adi­pos­i­ty­Dis­eases Leipzig. His research focus­es at genet­ic caus­es of obe­si­ty: he is asso­ci­at­ing obe­si­ty SNPs (point muta­tions, e. g. in the genes FTO, MC4R, BDNF) with altered brain struc­ture (VBM on T1-weight­ed MRI images). Fur­ther­more he analyse the asso­ci­a­tion of behav­ioral mea­sures and mea­sures of obe­si­ty like the body mass index (BMI). To assess also dif­fer­ent con­di­tions, under which the BMI can be explained, he use mul­ti­ple regres­sion with mod­els of medi­a­tion and moderation.
