Bibiana Rodríguez and Arbaz Kahn, from Colombia and India, respectively, are staying at the UBB in the context of studies led by Pablo Venegas and David Mora.
Two foreign researchers are visiting the Universidad del Bío-Bío (UBB) these days to collaborate with members of the Center for Mathematical Modelling (CMM) of the U. de Chile based in the city of Concepción.
Bibiana López-Rodríguez, academic of the Department of Mathematics of the U. Nacional de Colombia, Medellín, who, between June 23 and July 21, visits the CMM researcher and academic of the Department of Mathematics (DMAT) of the Faculty of Sciences of the UBB, Pablo Venegas Tapia, who details that “our motivation is to continue research work that we have together with researchers from the U. de Santiago de Compostela, Spain; in addition to initiating new research work”.

He is also a member of the DSALT Ring Project (ACT 210087) and explains that “we want to study the numerical approximation of a thermoelectric problem that models, for example, the behaviour of electric furnaces. This system of equations consists of the coupling of Maxwell’s equations with the heat transfer equation through the Joule effect”.
Venegas explains that “this is Bibiana’s third research stay; the first was funded by a Fondecyt project and the second by MWC. The previous visit resulted in a joint publication with José Querales, a graduate student of the PhD in Applied Mathematics at the UBB”.
“In this work”, Venegas emphasises , “we study a problem of fluid-structure interaction with axial symmetry that has applications to desalination processes by membrane distillation” and emphasises that this third visit was partially financed by López-Rodríguez’s house of studies, complemented by funds from the CMM.
Desalination applications
Meanwhile, David Mora Herrera, director of the DMAT of the UBB and member of the CMM and the Centre for Research in Mathematical Engineering, CI²MA, of the U. de Concepción, received Arbaz Khan from the Department of Mathematics of the Indian Institute of Technology Roorkee, India, between Tuesday 11 and Thursday 27 June, thanks to resources from the Regular Fondecyt project (1220881) that Mora heads.
“With Professor Khan”, Mora, also a researcher at CMM, explains “we have several collaborative works and several ongoing projects related to numerical discretisation using virtual elements of solid and fluid mechanics problems, with emphasis on problems modelling seawater desalination phenomena“.
Bibiana López y Pablo Venegas”We have recently submitted a paper on this topic to a specialised journal. Professor Khan’s visit was conceived in 2023, when we met at a conference in Seoul last August. Our collaboration came about thanks to Prof. Ricardo Ruiz (Monash U., Australia)”, says Mora.
Among the objectives of this stay, Mora highlights “making progress on these projects and being able to discuss future research projects”, as well as “strengthening collaborative ties with the research group”.
“In particular”, says Mora, “we are making progress on a collaborative work that is related to obtaining approximate vibration frequencies for a fluid-structure problem, as well as proposing an a posteriori error estimator for this spectral problem”.
The CMM researcher emphasizes that, being this the first visit of Prof. Kahn to our country, his host highlighted that he took the opportunity to “hold working meetings with researchers, students of the PhD in Applied Mathematics UBB (Alberth Silgado), postdocs (Nitesh Verma, Jesús Vellojín) and colleagues of our research group (Verónica Anaya, Felipe Lepe), in which possible collaboration topics were discussed, as well as possible scientific visits in the future to strengthen collaboration ties”.
