About me

I’ve wanted to be a psychologist for as long as I can remember. From a young age, I struggled with emotional dysregulation and intense feelings that often felt overwhelming. Growing up as an LGBTQIA+ person deeply influenced the therapist I am today. Experiencing alienation, loneliness, and the complexities of visibility gave me a profound understanding of the importance of self-knowledge, emotional awareness and social belonging. These early experiences shaped not only my personal growth, but also my professional calling: supporting others as they work through emotional difficulties and rediscover their strength, identity, and capacity to thrive. I completed my PhD in 2023, focusing on personality disorders, an area I’ve always found deeply meaningful and complex. I’m particularly interested in the depth of human experience: identity, relationships, emotional (dys)regulation, and the ways we learn to cope. In the last 11 years, I have focused my academic and clinical work on third-wave cognitive behavioural therapies, particularly Acceptance and Commitment Therapy (ACT), Compassion-Focused Therapy (CFT), and Dialectical Behaviour Therapy (DBT), as I believe these approaches offer essential tools for developing acceptance, self-compassion, and emotional regulation skills. I am currently a Professor of Clinical Psychology at Lusófona University (Porto, Portugal), where I teach and supervise future psychologists, striving to pass on the professional values and ethical principles that guide my own work as a clinician and researcher. My work is grounded in compassion, curiosity, and respect for each person’s unique story. I aim to create a space where people feel seen, affirmed, and genuinely safe to explore who they truly are.

Approach

Treatment Approaches
ACT: Acceptance and Commitment TherapyRecommended for those who want to stop fighting negative thoughts and learn how to live with more acceptance and focus on what really matters in life.
CFT: Compassion-Focused TherapyRecommended for those who want to be kinder to themselves and reduce negative self-talk, often using mindfulness techniques.
DBT: Dialectical Behavior Therapy Recommended for those who want to learn skills to manage intense emotions and improve their relationships, especially if they feel easily overwhelmed.
My therapeutic approach is integrative, evidence-based, and deeply relational. I draw primarily from third-wave cognitive behavioural therapies, while tailoring the work to each person’s unique history, personality, and needs. I value balancing structure with emotional depth to help people developing practical skills for regulation and coping, while also exploring identity, attachment patterns, and the meaning behind their experiences. Above all, I prioritise creating a collaborative, non-judgmental space where people feel safe enough to be vulnerable, curious about themselves, and open to change. I see therapy as a process of increasing awareness, strengthening emotional flexibility, and building a life that feels more aligned, compassionate, and authentic.

Experience

Clinical Experience Since 2015, I have been in clinical practice working with at-risk youth, university students, and adults experiencing anxiety, depression, and personality disorder traits. My clinical approach is grounded in evidence-based models, including Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT), Compassion-Focused Therapy (CFT), and Dialectical Behaviour Therapy (DBT). Research Experience Since 2018, I have also been involved in research focusing on emotion (dys)regulation strategies across diverse populations, including adolescents, adults, LGBTQIA+ individuals, and oncology patients. This work has explored emotional processes in the context of a range of psychological difficulties, from anxiety and depression to interpersonal challenges and eating-related problems.
