16. Hania Uscka-Wehlou (at the time Hanna) defended her thesis Digital lines, Sturmian Words, and Continued Fractions on 2009 September 25 at Uppsala University. Opponent: Damien Jamet. Her other advisors were Maciej Klimek, Gunilla Borgefors, and Mikael Passare.

    She has held several university positions, among them one as senior university lecturer at Uppsala University during two years, from 2017 up to 2019 August 13. From 2019 August 14, she held a permanent position as senior university lecturer at Mälardalen University. She decided to leave this position on 2021 May 18. On 2021 May 18 she was offered a position of the same type at Uppsala University, having been ranked first among twenty-three applicants. Three days later she declined this offer—she prefers to develop online courses at Udemy, an American massive open online course (MOOC) provider aimed at professional adults and students.

    Hania has received five awards:

    • The Royal Society of Sciences, Sweden's oldest academy, awarded her a Benzelius prize on 2010 August 31.

    While this prize is for her research, the following prizes were for her educational skills, being best-teacher awards.

    For the three awards mentioned below, it should be noted that the competitions were among all teachers and all subjects in the three engineering programs in the Faculty of Science and Technology of Uppsala University, not just mathematics:

    • On 2018 May 13 from the students at the Master Program in Engineering Physics;
    • On 2018 May 25 from the students at the Master Program in Electrical Engineering; and
    • On 2018 December 20 from the students at the Master Program in Chemical Engineering.
    In January 2019, the Student Union of the Faculty of Science and Technology of Uppsala University announced that she will be awarded the
    • Student Prize for best teacher of the Faculty och Science and Technology,
    thus now in a competition over all subjects and all teachers in the whole faculty, which comprises a third of Uppsala Unversity. The prize is awarded once a year.

17. Shiva Samieinia defended her thesis Digital Geometry, Combinatorics, and Discrete Optimization on 2011 January 21 at Stockholm University. Opponent: Rémy Malgouyres. Her other advisors were Julius Borcea up to 2009 April 08 and from that day on Rikard Bøgvad. She presented her Licentiate Thesis at a seminar on 2007 September 25 with Damien Jamet as the opponent.

    Shiva Samieinia applied to be a PhD student at Uppsala University but her application was turned down on 2005 February 01 by the Head of Department there. Instead, she was welcomed to Stockholm University by Mikael Passare, then Head of Department, at a meeting on 2005 September 09 and formally accepted as a PhD student at Stockholm University on the same day.

    She has worked as senior university lecturer both at the Royal Institute of Technology and Uppsala University. More recently, she was a senior university lecturer at Stockholm University, however with a time-limited appointment (2015 July 01 through 2017 June 15).

    From January 2019 Shiva Samieinia works at EnterCard Group AB, Stockholm.

    Shiva received a prize from The Ruth and Nils-Erik Stenbäck Foundation for Research, which was handed over at a ceremony in Helsinki on 2016 April 29. The amount of this scholarship is 30 kEUR.

18. Adama Arouna Koné presented his thesis with title page and full text Géométrie digitale utilisée pour la discrétisation et le recouvrement optimal des objects euclidiens (114 pages) on 2016 January 14 at l'Université des Sciences, des Techniques et des Technologies de Bamako (USTTB). Décision du Recteur; Rapport de soutenance; Procès verbal.

    His thesis was approved by the jury, which was chaired by Hamidou Touré of Université de Ouagadougou, and received the highest grade, Très honorable. I am happy that I could be present in Bamako at this important event.

    His other advisors were Ouaténi Diallo and Diby Diarra, both at l'Université des Sciences, des Techniques et des Technologies, and Gunilla Borgefors of Uppsala University. He was accepted as a doctoral student by a decision of la Faculté des Sciences et Technique (FAST), on 2011 October 05.

    Adama visited Uppsala to work with me the first time for four weeks, 2012 November 20 through December 17, and then for a second visit of two months, 2013 March 31 through May 30. His third visit to Uppsala was during the five months 2014 January 11 through June 12. The host for these visits was the Department of Mathematics.

    His fourth visit was from 2015 January 24 up to June 12, this time at the Department of Information Technology.

    All his visits to Sweden, totalling almost 13 months, have been supported by the International Science Programme (ISP), more precisely by its International Programme in the Mathematical Sciences (IPMS) and its network Partial Differential Equations, Modelling and Control.

    On 2015 December 29 his paper entitled "Covering a Euclidean line or hyperplane by dilations of its discretization" was accepted for publication in the Vietnam Journal of Mathematics. It was published online on 2016 June 03; in print in volume 45 (2017), no. 3, 351–368.

    He was nominated on 2017 November 23 by the Minister for Higher Education and Scientific Research to be Maître-Assistant at l'Université des Sciences, des Techniques et des Technologies de Bamako (USTTB). On 2018 January 08 he was nominated, again by the Minister for Higher Education and Scientific Research, to be Maître-Assistant at École Normale d'Enseignement Technique et Professionnel (ENETP), where he now teaches and does research.

I have been assistant advisor to the following four persons

• Robin Strand. Thesis: Distance Functions and Image Processing on Point-Lattices, defended on 2008 November 07 at Uppsala University. Opponent: David Coeurjolly. He was a graduate student in computerized image processing. Gunilla Borgefors was his principal advisor, Stina Svensson his second; I was his third. Now professor at Uppsala University, Department of Information Technology.
• Abtin Daghighi. Thesis: Regularity and Uniqueness-Related Properties of Solutions with Respect to Locally Integrable Structures, defended on 2014 May 21 at Mid Sweden University. Opponent: Jürgen Leiterer, Humboldt-Universität zu Berlin. Abtin was a graduate student at Mid Sweden University (Campus Sundsvall) since 2009 July 01, financed by the Graduate School in Mathematics and Computing. His principal advisor was Egmont Porten, I was second advisor, and Stefan Borell his third advisor (effective 2011 November 30; before that date it was Cornelia Schiebold). Abtin presented his licentiate thesis on 2012 December 18. It has the title The maximum principle for Cauchy–Riemann functions and hypocomplexity. The appointed opponent was Jürgen Leiterer.
