Demografoa naiz eta nire ikerketa-lanak datuak, metodologia formala, hilkortasuna, biztanleriaren osasuna, datuen bistaratzea eta zientzia irekia ditu oinarritzat batez ere.

Demografian doktorea naiz (UAB, 2013), doktore ondorengoa egin nuen UC Berkeley-ko Human Mortality Database taldean, datu-azpiegituren programazioan eta datu-kudeaketa lanetan, eta ikertzaile gisa aritu nintzen Alemanian Rostock-eko Max Planck Institute for Demographic Research-en, non oraindik ere ikertzaile gonbidatu naizen. 2020an Ikerbasque Zientziarako Euskal Fundazioak eskeintzen dituen Research Fellow postuetako bat lortu nuen, eta horri esker, 2021ean OPIKen hasi nintzen ikertzaile lanetan.

Nire lanak osasunean dauden desberdintasunak neurtzeko zeharkako metodoen garapenean du ardatz: bizitza-ibilbideetan oinarrituta, osasunaren neurketak eta deskonposizio metodoak garatuz, osasunaren eta bizitzako iraupenaren desberdintasunak ezaugarritzea dut helburu. 2020an COVerAGE-DB datu-basea sortzen hasi nintzen, COVID-19 kasuak, heriotzak, test-frogak eta txertoak adinka biltzen dituen nazioarteko datu-basea. COVerAGE-DB-ek OME, Nazio Batuak edo UNICEF bezalako erakundeei pandemiaren jarraipena egiteko ahaleginetan lagundu die. COVID-19aren gehiegizko hilkortasuna neurtzeko eta aztertzeko sortutako OME eta Nazio Batuetako Aholku Talde Teknikoaren parte naiz, eta bertan, 2020-2021ean COVID-19aren ondoriozko heriotza zuzen eta kausa guztien gehiegizko heriotzak adinaren arabera karakterizatzen laguntzen dut batez ere. Gaur egun, demografia eta osasun-desberdintasunei buruzko ikuspegi berriak gehitzen ari naiz nire ikerketa-zerrendan.

R programazioa, demografia eta metodo demografikoak, eta datuen bisualizazioan eman ohi ditut ikastaroak aldizka, besteak beste BSSD, EDSD, PHDS, KOSTAT-UNPFAk antolatutako Udako Biztanleriaren Mintegian eta eskaturiko beste ikastaro batzuetan.
