Prof. Ven­tikos’ research focus­es on trans­port phe­nom­e­na and flu­id mechan­ics, as they are applied to bio­med­ical engi­neer­ing prob­lems, ener­gy, inno­v­a­tive indus­tri­al process­es and bio­com­plex­i­ty. Areas of research include arte­r­i­al haemo­dy­nam­ics and tis­sue remod­el­ling (with an empha­sis on vas­cu­lar dis­eases, like aneurysms), cere­brospinal flu­id dynam­ics, shock-induced bub­ble col­lapse, droplet gen­er­a­tion and depo­si­tion, tar­get­ed drug deliv­ery, swirling flows, chaos, mix­ing and dynam­i­cal sys­tems, organo­gen­e­sis and tis­sue engi­neer­ing, micro- and nano-tech­nolo­gies. Com­pu­ta­tion­al mod­el­ling is at the cen­tre of his research, which spans the spec­trum from fun­da­men­tal to applied. Yian­nis Ven­tikos is the Kennedy Pro­fes­sor of Mechan­i­cal Engi­neer­ing and the Head of the Mechan­i­cal Engi­neer­ing Depart­ment at Uni­ver­si­ty Col­lege Lon­don. He has worked or stud­ied in Greece, France, the USA and Switzer­land. Prof. Ven­tikos has estab­lished the Flu­idics and Bio­com­plex­i­ty Group that cur­rent­ly involves more than twen­ty researchers, most­ly at the doc­tor­al and post­doc­tor­al lev­el. He has pub­lished about 100 papers in peer-reviewed sci­en­tif­ic jour­nals, has con­tributed chap­ters in 5 books, has pre­sent­ed more than 200 papers in inter­na­tion­al con­fer­ences and work­shops and has filed six inter­na­tion­al patents to date. He is the senior aca­d­e­m­ic founder of a spin-out com­pa­ny and con­sults inter­na­tion­al­ly in top­ics of his exper­tise. He has served as a review­er for more than 50 aca­d­e­m­ic jour­nals as well as for text­book and mono­graph pub­lish­ers. He is on the edi­to­r­i­al board of four jour­nals, and on the sci­en­tif­ic and/or organ­is­ing com­mit­tee of numer­ous inter­na­tion­al con­fer­ences and work­shops.

Daniel stud­ies how shear stress trig­gers the acti­va­tion and nuclear translo­ca­tion of NF-κB in vas­cu­lar endothe­lial cells. NF-κB is a key pro­mot­er of inflam­ma­to­ry respons­es and plays a piv­otal role in cell growth, sur­vival and apop­to­sis. Hence a rela­tion­ship between NF-κB and shear stress would con­tribute to a bet­ter under­stand­ing of car­dio­vas­cu­lar dis­eases. We inves­ti­gate the effect of tem­po­ral and spa­tial shear stress gra­di­ents on the acti­va­tion of NF-κB with in-vit­ro exper­i­ments in col­lab­o­ra­tion with Prof. Rob Krams from Impe­r­i­al Col­lege Lon­don and cre­ate a numer­i­cal mod­el to pre­dict inflam­ma­to­ry respons­es in com­plex ves­sel geome­tries.

Sole­ly using microflu­idic devices to manip­u­late microbub­ble size expe­ri­ences lim­i­ta­tions espe­cial­ly with very vis­cous solu­tions, hence cap­i­tal­is­ing on the well under­stood con­cept of bub­ble res­o­nance, var­i­ous types of elec­tric fields are inves­ti­gat­ed to facil­i­tate bub­ble break-up. A com­pu­ta­tion­al mod­el will be cre­at­ed to sim­u­late the entire exper­i­men­tal set-up and enable bet­ter under­stand­ing of  flu­id mechan­ics of the flow and the elec­tro­hy­dro­dy­nam­ic inter­ac­tions

Blood Flow and the Devel­op­ment of Aneurysms: Nov­el Inves­tiga­tive Meth­ods: The com­plex inter­ac­tion between a deformable body and a sur­round­ing flu­id such as in the case of a deform­ing atri­al wall and blood flow is referred to as flu­id struc­ture inter­ac­tion (FSI). Exper­i­men­tal stud­ies involv­ing aneurysms have typ­i­cal­ly only employed flu­id flow mea­sure­ments with rigid mod­els. This PhD will present a nov­el tech­nique where simul­ta­ne­ous flu­id flow and atri­al wall defor­ma­tion mea­sure­ments will be car­ried out using the meth­ods of Par­ti­cle Image Velocime­try and Dig­i­tal Image Cor­re­la­tion respec­tive­ly. This work is there­fore pre­sent­ing a nov­el com­bined mea­sure­ment tech­nique that has the poten­tial to yield insight into the under­stand­ing of the patho­phys­i­ol­o­gy of aneurys­mal ini­ti­a­tion, growth and even­tu­al rup­ture.

Sim­u­la­tions of shock­wave-bub­bles inter­ac­tions: The project aims to inves­ti­gate com­pu­ta­tion­al­ly the inter­ac­tions of shock waves with mul­ti­ple gas-filled bub­bles in a liq­uid medi­um. A front-track­ing approach is to be employed, which allows for an explic­it track­ing and accu­rate rep­re­sen­ta­tion of the gas-liq­uid inter­face. The (three-dimen­sion­al) sim­u­la­tions will be car­ried out using a freely-dis­trib­uted and well-val­i­dat­ed code, devel­oped at Stony Brook Uni­ver­si­ty. A “library” of results will be con­struct­ed and an attempt to form empir­i­cal laws that describe the col­lapse process and the inter­ac­tion between the gas bub­bles will be car­ried out.
