Tech­ni­sche Uni­ver­si­tät Dres­den - Clus­ter of Excel­lence ‘Cen­ter for Advan­cing Elec­tro­nics Dres­den’ (cfaed)

The TU Dres­den is one of ele­ven Ger­man uni­ver­si­ties that were iden­ti­fied as an “excel­lence uni­ver­sity”. TUD has about 36.500 stu­dents and almost 5319 employees, 507 pro­fes­sors among them, and, thus, is the lar­gest uni­ver­sity in Sax­ony, today.

Having been com­mit­ted to sci­en­ces and the engi­nee­ring before the reuni­fi­ca­tion of Ger­many, TU Dres­den now is a multi-disci­pline uni­ver­sity, also offe­ring huma­nities and social sci­en­ces as well as medi­cine.

About the “Bio­lo­gical Algorithms group”
How do struc­tures form in cells and tis­sues? The mis­sion of our “Bio­lo­gical Algorithms group” is to under­stand phys­ical prin­ciples of self-assembly and self-organ­iz­a­tion in liv­ing mat­ter. Top­ics in-clude the spon­tan­eous form­a­tion of pat­tern in the cyto­skel­eton of cells, in tis­sues, and organ-isms. In our the­or­et­ical research, we com­bine non­lin­ear dynam­ics, stat­ist­ical phys­ics, and compu-tational phys­ics to under­stand phys­ical mech­an­isms of bio­lo­gical func­tion, and its robust­ness in the pres­ence of noise and per­turb­a­tions, while closely col­lab­or­at­ing with exper­i­mental part­ners.
More inform­a­tion on cur­rent research can be found at Our small group con­sists of enthu­si­astic stu­dents from dif­fer­ent coun­tries. All group meet­ings are held in Eng­lish and no know­ledge of the Ger­man lan­guage is required.

Work­ing field:

We are hir­ing a PhD stu­dent for a pro­ject in The­or­et­ical Bio­phys­ics, to under­stand how micro-scopic force-gen­er­at­ing units in our mus­cles self-assem­ble dur­ing devel­op­ment: Every mus­cle cell in your body con­tains highly reg­u­lar myo­fib­rils, which pro­duce act­ive mus­cle forces. Each myo­fib­ril is built by a chain of sar­come­res, com­posed of actin fil­a­ments and myo­sin molecu­lar motors, lin­ked tog­e­ther by gigan­tic titin springs. The myo­fib­rils are act­ive “bio­lo­gical crys­tals” and any alter­a­tions of their reg­u­lar archi­tec­ture are lin­ked to dis­ease sta­tes. Yet how these myo­fib­rils assem­ble dur­ing devel­op­ment is poorly under­stood in terms of phys­ical mech­an­isms.
Pre­vi­ously, we pro­posed a math­em­at­ical model of how actin and myo­sin fil­a­ments self-assem­ble into reg­u­lar sar­come­ric pat­terns by a com­bin­a­tion of act­ive forces and pass­ive cross­link­ing (Frie-drich et al. PLoS Com­pu­ta­tio­nal Bio­logy, 2012). Based on this, we want to deve­lop in this pro­ject com­puter sim­u­la­tions of a bundle of actin, myo­sin, and titin, in order to under­stand the role of act­ive ten­sion and fil­a­ment elasti­city in sar­comere self-assem­bly. You will for­mu­late altern­at­ive phys­ical mech­an­isms in terms of math­em­at­ical mod­els. You will imple­ment mech­an­isms, e.g. as agent-based sim­u­la­tions, with spe­cific inter­ac­tion rules for the dif­fer­ent fil­a­ments. You will com-pute phase dia­grams and derive test­able pre­dic­tions. In addi­tion to sim­u­la­tions, you can coarse-grain the inter­ac­tion model to devise a mean-field the­ory of sar­come­ric pat­tern form­a­tion. Final-ly, you can com­pare the­ory pre­dic­tions to quant­it­at­ive exper­i­men­tal data.
This PhD the­sis will con­sti­tute the the­ory part of a the­ory-exper­i­ment col­lab­or­a­tion with the la-bor­at­or­ies of Frank Schor­rer (IBDM, Mar­seil­les) and Oli­vier Pour­quie (HMSB, Bos­ton). You will par­ti­cip­ate in reg­u­lar inter­na­tio­nal pro­ject meet­ings. The exper­i­men­tal part­ners will pro­vide high-res­ol­u­tion time-lapse micro­scopy data of devel­op­ing myo­fib­rils, as well as molecu­lar force-sen­sor data for live force meas­ure­ments in devel­op­ing mus­cle fibers. Based on this data, we will quan­tify the gra­dual emer­gence of sar­come­ric pat­terns using con­cepts from Soft Con­den­sed Mat­ter Phys­ics (nema­tic and smec­tic order para­met­ers) to link the­ory and exper­i­ment. Full fund­ing includ­ing tra­vel funds is avail­able from the pres­ti­gi­ous Human Fron­tier Sci­ence Pro­gram.
