+Marten Haitjema successfully defended "`Estimating fall probability in cycling
+<http://resolver.tudelft.nl/uuid:b7a3ff8d-de2b-47ee-ac05-61c34c1eac23>`_" on
+December 14, 2023. Marten identified the linear dynamics of a robotically
+balance assisted bicycle showing that the lean rate feedback controller can
+stabilize the bicycle at very low speeds and that the time constant of the
+instability is significantly reduced when there is a rider onboard. He then
+executed an experiment to determine the probability a rider will fall when
+perturbed with different magnitude forces at the handlebar. He showed that the
+perturbation magnitude and number of prior perturbations were the most
+important factors in determining whether one would fall. Lastly, he used these
+probabilities to predict a likely reduction in fall probability when the
+balance assist system is activated.
+
+Marten was co-supervised by Leila Alizadehsaravi (TU Delft) and Jason K. Moore
+(TU Delft) with assistance from Maarten Pelgrim (Gazelle), Sierd Heida
+(Gazelle), Felix Dauer (Bosch), and David Gabriel (Bosch). Everyone at the
+bicycle lab is very proud of Marten and wishes him the best in his next
+adventures.
