As a researcher, my main interest are the bioproduction of high-value-added biomolecules and protein engineering.
Abou is known as the Cake Expert due to the number of sweet goodies that he has brought for the other SEMsters to enjoy. They now grew spoiled and demand cakes whenever they can.
Even if he joined the Enzyme Engineering and Structural Biology group, he is still 50% (precisely 50%) part of the SEM group. Therefore, the SEM group can potentially claim ownership of up to 50% of the cakes he brings to the lab.
Abou might not notice immediately that you left for some extended period, but he will be excessively happy to see you back.
As a French citizen, he will honestly and professionally criticize any dish you bring to him. He might also question some of your habits out of curiosity.
Abou is probably the first human being to be an introvert and an extrovert at the same time. He can stay at home watching animes for three days or go for a three-day long bike trip, or go partying and meeting new people but not for three days—he has limits you know.
