Dr. Kārlis Freivalds ir vadošais pētnieks Elektronikas un datorzinātņu institūtā. Absolvējis Latvijas Universitāti (Rīga, Latvija), ieguvis zinātņu doktora grādu datorzinātņu studiju programmā. Viņš ir 30+ zinātnisku publikāciju un 7 patentu pieteikumu autors. Ir bijis iesaistīts dažādos zinātniskos un industriālos projektos datorredzes, mākslīgā intelekta, grafu algoritmu, bioinformātikas un kvantu skaitļošanas jomās, kur vadījis pētniecisko darbu kā arī programmatūras izstrādi un ieviešanu ražošanā. Galvenās pētījumu jomas ir mākslīgais intelekts, datorredze, robotika un mašīnmācīšanās, pēdējā laikā uzmanību veltot dziļajiem neironu tīkliem, kur ir izstrādājis vairākas jaunas neironu tīklu arhitektūras ātrai virkņu apstrādei, algoritmiskiem uzdevumiem un NP-sarežģītu problēmu risināšanai. Viņš ir arī docents Latvijas Universitātes Datorikas fakultātē, kur pasniedz attēlu apstrādes un datorredzes algoritmu programmēšanu.
