EducationDelft University of Technology Delft, The NetherlandsPH.D. IN CONTROL ENGINEERING: “CLOSED-LOOP WIND FARM CONTROL” Aug. 2016 - PRESENT

• Promoters: prof. dr. ir. J.W. van Wingerden, prof. dr. ir. M. Verhaegen• Research description: “Due to lack of knowledge about the environment and tough-to-model flow and turbine dynamics at a range ofspatial and temporal scales, the surrogate models currently used for model-based wind farm control do not suffice for annual opera-tion. This research addresses this scientific gap by the development of real-timemodel calibration algorithms, enabling the synthesis ofclosed-loop control algorithms at a farm level which treat the entire wind farm as a comprehensive real-time optimization problem.”

Key Engineering ProjectsEuropean Horizon 2020 project: “Closed-LoopWind Farm Control” (CL-Windcon) Delft, The NetherlandsCORE PARTNER, AND LEAD FOR SEVERAL DELIVERABLES Nov. 2016 - PRESENT

• This project addresses the advanced modeling and the synthesis of open- and closed-loop control algorithms for a wind farm bytreating the entire farm as a comprehensive real-time optimization problem. The synthesized control solutions will be validatedleveraging high-fidelity data from simulation, scaled wind tunnel experiments, and field testing. My main responsibilities includethe development of the open- and closed-loop control algorithms, and their validation using data made available by the partners.

Confidential research project with an industrial partner Delft, The NetherlandsLEAD ROLE IN COLLABORATION WITH ONE OTHER PHD STUDENT Oct. 2018 - PRESENT

• Duringmy PhD, I helped to spark interest, plan and execute a consultancy project with a large industrial partner. This project enablesme to improve my soft skills such as project planning, team coordination, and how to have interdisciplenary discussions, as well asimprove my understanding of the relevant challenges in the research field.

Confidential research project with an industrial partner Boulder, Colorado, United StatesSUBCONTRACTED BY NREL Jan. 2017 - May 2017

• During my PhD, I was subcontracted by the U.S. National Renewable Energy Laboratory (NREL) to work in a confidential researchproject for an industrial partner. For this, I spent two months at the National Wind Technology Center in Boulder, Colorado. Thiscollaboration not only strengthened the link between TUDelft and NREL, but also gave practical insights that have allowed me totailor my research to better meet the needs of industry.

Master’s thesis Boulder, Colorado, United StatesSTATE ESTIMATION FOR A MEDIUM-FIDELITY WIND FARM MODEL Dec. 2015 - June 2016

• The goal ofmymaster’s thesiswas todesign a computationally efficient state observer forWindFarmSimulator – a surrogatewind farmmodel based on a discretized set of 2DNavier-Stokes equations. The challenge lies in having observer updates that take less than onesecond to compute, while accounting for themodel’s complicated, time-varying dynamics and large size (typically thousands to tensof thousands of states). Under supervision of prof.dr.ir. J.W. vanWingerden, I have performedmy research abroad at the University ofColorado, Boulder (United States), with local supervision of prof. dr. L.Y. Pao. This work was rewarded with grade 9.0.

Extracurricular ActivitiesPhD Faculty Council Delft, The NetherlandsBOARD MEMBER Nov. 2017 - PRESENT

• The “3mE PhD Council” organizes monthly events for approximately 300 PhD students of the Faculty of Mechanical, Maritime andMaterials Engineering. We enable people to learn, connect, and improve their PhD experience at the Delft University of Technology.

• I assist and often take the lead in the organization of the monthly faculty talk, in which we host a variety of speakers and serve lunch.• I have led the organization of a 4-week meditation workshop to improve productivity and reduce stress for PhD students.• I have played an important role in the organization of the annual sports day for the 3mE PhD students in May 2018 and May 2019.

CU Boulder’s International Festival Committee Boulder, Colorado, United StatesSUBCOMMITTEE CHAIR Sep. 2015 - Apr. 2016

• Duringmy time as a visiting researcher in Boulder (see: Key Engineering Projects), I have volunteered at a number of activities focusedon celebrating diversity and bringing students from different backgrounds together. For “IFest 2016”, a yearly recurring internationalfestival organized by students and for students, I have chaired two subcommittees out of five total. This festival typically attracts over6,000 guests andwas free to the public. Throughout the day, nationalities fromall over theworld are represented by students hostingtheir country’s ownpersonalizedbooth. Furthermore, there are variousperformancesby student groups related to their homeculture.

• Amongmy responsibilities were supervision of approximately 10 CU students, communicating with external student groups, organiz-ing the contents and layout of the day, and designing graphics to publicize the event (e.g. posters, handbills, table tents, and flyers).

Albert Schweitzer Ziekenhuis (Hospital) Dordrecht, The NetherlandsEMPLOYEE INTERNAL AND EXTERNAL LOGISTICS Aug. 2010 - Aug. 2015

• During weekends, I solely carried the responsibility of the logistics department, which includes but is not limited to: the internaldistribution of goods, external transportation of goods, and management of waste and laundry.
